Group B is a veritable group of death at this tournament, featuring the Netherlands, Germany and Denmark, the three former champions of the European Championship, as well as Portugal, a traditional powerhouse in European football.

The Orange are still the stars, the uncrowned king is still the favourite, and after the transformation of Basten and Van Marwijk, the Dutch team has been getting better and better in recent years, and is getting closer and closer to the championship.

Van Marwijk replaced Basten after the 2008 European Championship and became the head coach of the Dutch national team, after taking office, he changed the traditional 433 formation of the Netherlands into 4231, and achieved remarkable results, and led the team to win the runner-up in the World Cup in South Africa.

In terms of lineup, in the goalkeeper position, Stekelenberg's main position is unshakable, while Worm and Krull, although they are the main players in Swansea City and Newcastle in the Premier League, are destined to only play the role of accompanying the prince to study.

At the back, Donny van de Wiel, Heitinga and Mathieson were all mainstays during the World Cup in South Africa, and if nothing else, they will remain indispensable in the Orange defence, while the left flank position is likely to be dominated by the retirement of veteran Van Bronckhorst.

In midfield, Van Bommel and De Jong, the two main players during the World Cup, will still occupy the starting midfield position, and Stroman, who has performed well in the Eredivisie this season, will be the main substitute. Sneijder remains the playmaking soul of the Orange midfield, with plenty of options on either wing, with Van der Vaart, Kuyt, Arjen Robben and Afellae all available for Van Marwijk.

As for the attack, Huntelaar and Robin van Persie can be up front alone and can also play together, but who will play the leading role, with last season's Premier League and Bundesliga top scorers, Van Marwijk must solve this happy problem as soon as possible.

The heart of the Dutch squad will undoubtedly be Sneijder, who has been a regular midfielder for the Dutch squad since the 2006 World Cup, and has been named in the 11-man squad for the last two continental tournaments.

Another player to watch is Peter Pan, who has already played for the Dutch national team in the last four international tournaments and is an integral part of the Orange team's attacking line.

Of course, there is another person who can not be mentioned, that is, Arsenal captain Van Persie, his last two seasons, in the club performance can be described as infinite, although the Gunners have never won the Premier League crown, but Van Persie's performance has convinced everyone, this European Cup is also Van Persie's fourth continental competition, missed the opportunity to win the cup in the 2010 World Cup in South Africa, and now the maturing Dutch team is ready to attack the championship in this European Cup.

Twenty-four years ago, the Orange Army had world-class stars such as Koeman, Ruud Gullit, Basten and Rijkaard, although they lost 0-1 to the former Soviet Union in the first game of the group stage, and knocked England and Northern Ireland in the second two games to qualify for the group, and Van Basten scored a hat-trick in the second game against the Three Lions. In the semi-finals, it was Basten who stepped up when the two sides were tied 1-1 and scored the decisive goal in the 88th minute. In the final, the Netherlands finally found a chance to take revenge on the former Soviet Union, with Gullit's header and Basten's zero-degree world wave making it easy for the Orange to be crowned. Since 1988, the Netherlands have not missed the European Championship finals and have reached the quarter-finals for six consecutive years.

In this Cup, the Dutch team fell into the so-called group of death as four years ago, and the old rivals Germany, Portugal and Denmark in the same group, although from the perspective of historical confrontations, the Netherlands against Germany and Portugal are inferior, only facing Denmark has a slight advantage, but do not forget that four years ago, the Orange Army also easily broke out of the group of death, 3:0 victory over Italy, 4:1 victory over France, 2:0 victory over Romania, the whole process is hearty.

The goal of the Dutch team in this European Championship is to win the championship, of course, the premise of wanting to achieve better results is that the Netherlands can overcome the crux of the unstable defensive line, find the most suitable candidate for the main left gate as soon as possible, adjust the state of the midfielders, and solve the coexistence problem of the two golden boots of the striker, Van Persie and Huntelaar, only by doing this, the Orange Army can replicate the journey of winning the championship 24 years ago and win the Delaunay Cup again in Eastern Europe.

In Group B, the weakest is undoubtedly the fairytale kingdom Denmark, the Danish team that fell into the group of death, it is obviously very difficult to replicate the miracle of 20 years ago, but the Scandinavians can play the role of "spoiler", and even the final "judge" of the group.

Danish coach Olsen has been in charge of the Danish national team since 2000 and has led the team to the 2002 and 2010 World Cups, as well as the 2004 and 2012 European Championships.

Controlling the ball, playing flexibly and maintaining a strong vitality is what Olsen has given to Danish football.

After the World Cup in South Africa, Denmark's exit made him doubt and examine his football philosophy, and the outside world once thought that he would not get a contract extension from the Football Association.

But with Denmark comfortably topping the qualifiers, it was seen that the Danish team, known for their beautiful play with short passes, was back.

The Danish Football Federation has also given up on finding a new head coach and has completed a contract extension with Olsen, which means that his football philosophy will be further implemented.

In this European Cup, the Danish team withdrew with many veterans, mainly post-80s players, with an average age of 25 years old, and the Danish team, which has always given people a sense of aging, also unexpectedly swept a storm of youth, and there are even young players born in the 90s such as Eriksen and Okere in the squad.

In the goalkeeper position, Manchester United goalkeeper Lindegaard will be the starter, and Kasper, the son of the amazing goalkeeper Schmeichel. Schmeichel was also selected for the national team for the first time and competed in international competitions.

At the back, Ager and Kjaer, who play for Liverpool and Roma, have been the main centre-back duo for Denmark in recent years, with old internationals Jacobson and Paulsen on the flanks.

In midfield, the Danish team has Stuttgart's main Quest, and the "New Gravesson" Zimlin, the Nordic demon Eriksen, and the wingers Romedal and De Ghly are also unshakable.

Arsenal striker Bendtner will continue to be an important lone arrow, Bendtner's technical front, and full of impact, when he joined Arsenal, he was even hailed as the new Degan, and his performance will also be directly related to the final trend of Denmark's European Championship.

Among the team, the most anticipated is the teenager Eriksen, who is regarded as the most anticipated demon in Northern Europe, Eriksen is the main midfielder of the Danish team, the 92-year-old star was voted the Danish Footballer of the Year last year, and his bizarre passing can tear apart the opposition defence in an instant.

Bright-eyed, intelligent and studious, with a balanced left and right foot, an active runner, and his elegant and relaxed style of play and national team experience have sometimes compared him to Danish football legend Laudrup.

One of the hottest newcomers in Europe, Eriksen has received offers from major clubs from time to time, and his presence can provide the Danish team with the energy and creativity that they lacked.

Denmark has never been a football powerhouse, they are better at badminton, but the 1992 European Championships will make every Dane proud for a lifetime.

At that time, Yugoslavia was disqualified due to sanctions due to the civil war, and the second team in the group, Denmark, was urgently called up as a substitute. Laudrup refused to compete due to disagreements with the coaching staff, and the main player Vilfort had to return to Denmark from the stadium in Sweden again and again to visit his seriously ill daughter.

Denmark drew 0-0 with England in the first game of the group stage and lost 0-1 to Sweden led by Brolin in the second, and it was not until the final game of the group stage against France that the Danish fairy tale officially played out, with goals from Larsson and Elstrup knocking France out of the competition.

Denmark's opponents in the semi-finals were the Netherlands, and the two sides drew 2-2 after 120 minutes, scoring goals from Larsson, who joined the Danish team as a substitute, and finally in the penalty shoot-out, Schmeichel saved Van Basten's penalty to take Denmark to the final.

In Gothenburg, Sweden, the Danes faced Germany coached by Vogts in the final, and the Danish team, which had already made a fortune, fought with a relaxed mentality, and finally helped Denmark defeat the mighty German team 2-0 with goals from Jensen and Werford, and unbelievably lifted the Delaunay Cup.

Denmark fell into the group of death composed of the Netherlands, Germany and Portugal, and the qualification situation is in jeopardy, but most of the Danish team from coaches to players have received Dutch football education, or are currently playing in the Eredivisie, and the concept of Dutch football has influenced the football career of head coach Olsen for nearly four decades, so although the overall strength of the Netherlands is stronger than Denmark, the Danes who are familiar with Dutch football are also likely to score against their opponents.

Portugal and Denmark have experienced the World Cup in South Africa and the European Championship qualifiers together, in the qualifiers, the Danes won two games to win the group and qualify for the top of the group, so the Danes have a certain psychological advantage against Portugal.

Denmark's current forward ability may not be able to break through the German team's steel defense, but if the first two group games go smoothly and the last game against Germany with a relaxed mentality, the Danish team still has a chance to score based on the previous record of equal wins and losses between the two sides.

Who is the most vocal team in this tournament?

In the case of Digan who was largely scrapped, it was undoubtedly the German team.

Since beating England and Argentina in the 2010 World Cup, a new generation of German players has gradually stepped onto the world stage, which has caused Loew to start a sweet trouble, and although the starting framework has been reached, there are still plenty of talent waiting for the German team to get their chance.

After the 2006 World Cup, Klinsmann left the German team, and his assistant Loew took over the coaching whip and became the coach of the German team.

As Klinsmann's assistant, Loew pushed the team's tactical reforms, and the German team, which had always given the impression of being a "head team", gradually transformed into a technical team based on the feet.

In 2006, Loew helped Klinsmann achieve the revival of German football, in 2008 he led the team alone for the first time in the competition, although the results were not ideal, but to reach the semi-finals, it is very rare, in 2010 Loew continued to lead the team to the World Cup, the German team's style of play is becoming more and more mature, but unfortunately met the final champion team Belgium early, failed to enter the semi-finals, and now the German team has once again become the world's top team, Loew is also looking forward to leading the team to the top of Europe.

Since the 2010 World Cup in South Africa, Loew has changed the German team's tactics from 4-4-2 to 4-2-3-1, and has been used to this day, when Loew changed the 4-2-3-1 formation mainly because the German team's defensive strength was limited at that time, and had to use two backs to protect the back. And the lack of excellent strikers is also one of the reasons for Loew's change of formation. But the current German team still uses 4-2-3-1, mainly because of the blowout explosion of midfielders, Loew can only use this lineup to maximize the German midfield advantage and control the rhythm in the game.

In terms of lineup, the goalkeeper should be the most reassuring position in the German team, whether it is the starting goalkeeper Manuel Neuer, or the substitute goalkeepers Wiese and Ziller, they all have the quality to become the main goalkeeper of other national teams.

Neuer, in particular, if he was just a rising star in the 2010 World Cup in South Africa, then after two years of league baptism, Neuer has become one of the world's best goalkeepers, and with him in front of goal, the German team's defense is reassuring.

Compared to the back line at the 2010 World Cup, Loew's backline is full of variables, and in the left-back position, captain Lahm should have been the best choice, but with Germany now not having a right-back of his level, Lahm is likely to move to the right and let Schmelzer play as the main left-back. Of course, Loew could also keep Lahm at left-back and Bayern defender Boateng at right-back. In addition to the full-backs, the selection of central defenders is also unknown, Bayern central defender Bad Stuber has occupied a main position, the other will be created between Hummels and Mertesacker, Mertesacker's advantage is his experience in the tournament, and Hummels has been better at club this season, as well as the versatile Schalke captain Hevedes, who can be a wide but clearly better in the central defensive position.

Midfield is Germany's most extravagant position right now, and before the 2010 World Cup in South Africa, Ballack and Tresch withdrew due to injury, which once made Loew anxious. The current German team has a lot of talent at their disposal in the midfield position. At the back, the vice-in-command of Schweinsteiger and Khedira almost locked in the main position, and the duo's midfield combination was both offensive and defensive. In the midfield position, Loew was the only player in the World Cup in South Africa who was still young Ozil who had creativity, and now Loew has the already star Ozil, the maturing Kroos, and the supernova Gotze. On the flanks, Loew has Podolski and Reus, who have excellent goalscoring ability, on the left, and Muller and Schurrle on the right, and the biggest surprises in this edition of the list are Gundogan and Lars. Bender, who has become a tactical core at Bayer Leverkusen and Borussia Dortmund, can never be just a spectator at the European Championships.

Up front, the double insurance of veterans Klose and Gomez is also enough, but it is still undecided who will be the starting striker of the German team. Klose has been a regular in the German squad for 10 years since his rise to prominence at the 2002 World Cup, and experience and awareness are the veteran's greatest strengths. And Gomez, although Bayern regards goals as a mustard, but the rough technique and the "soft foot" in the tournament hinder Bayern's squad dominance.

At present, the captain of the German national team, Lahm, has become the spiritual leader of the German team from a young player, and before the 2010 World Cup in South Africa, Lahm, who temporarily took over the captain's armband, has now become the absolute leader of the German team.

At Bayern this season, Lahm played at left-back in the first half and right-back in the second, and he was airtight on both flanks and absolutely sharp in attack.

Lahm's ease of moving around the flanks also gave Loew more options, as the Germans lacked a good right-back. In the situation, Lahm seems to be the best result at right-back.

Rahm's team-mate at Bayern Munich, Schweinsteiger, was a steel barrier in front of the German backline, having been with the team through the 2004 Euro slump and returning home in Euro 2008. As a playmaker midfielder, although Piggy's skills are not as good as Xavi's and his defense is not as good as Khedira's, it is his all-round and big-picture vision that makes him one of the world's top midfielders.

Although Lahm and Schweinsteiger are not very old, they are already veterans in the current national team, and the same rising stars have nothing to look forward to.

Gotze is the biggest surprise in German football in recent years, known as a rare "supernova" in German football, the young Gotze in Dortmund's rapid offensive play, has achieved rapid growth, accurate passing, smart running, commendable is that the young Gotze also has a strong physique, in the game the young player has learned to use their strength, Loew has stated that Gotze will have a place in his lineup, the German supernova's first major trip is worth looking forward to.

As the most consistent team in European football, the German team has won the World Cup three times and has also won three crowns in the European Championship.

Now, after a youthful reform and tactical revolution, the German team has seen a full recovery, playing commendably at Euro 2008, only to lose to Belgium with Digan in the semi-finals.

The last team in Group B is Portugal with a golden mulro, and the young coach Bento took over the coaching whip of the Portuguese coach after the team's poor record during the European Championship qualifiers and the precarious situation of qualifying, and finally led Portugal to defeat Bosnia and Herzegovina in a powerful play-off, and after missing the last European Championship, they qualified for the 2012 European Championship.

Bento, who is known for his "strict management", did not win over many people when he was in charge of Lisbon, and his overly defensive style did not win over many people.

But in Portugal's seemingly "eventful" position, the 42-year-old young coach has led Portugal to successive victories and became the youngest coach in history to lead Portugal to a major competition.

In terms of the team's lineup, Benfica goalkeeper Eduardo will be the team's main goalkeeper if nothing else, and Bruno Bruno will be the team's main goalkeeper at the back. Alves and Pepe will be the backbone of the Portuguese backline, with Coentrão playing at left-back. Whether a backline can help Portugal emerge from the group of death will only be proven by the game.

In midfield, despite the presence of Moutinho and Merreles, these two players are not the kind of creative players, lacking a single pass that can tear apart the opposition backline, and contributing more to the team is to consolidate the team's defense and build a barrier in the midfield, which is also a major disaster for Portugal.

In terms of strikers, Camuro and Nani are separated from each other, so who can be qualified as the team's center forward has become a problem, although Postiga has a good performance in the European preliminaries, but the lack of experience in the tournament is one of its major shortcomings, and Almeida, Quaresma and Varela do not belong to the kind of strikers who can reassure the manager, although the young Oliveira is full of impact, but does not have the starting strength, if Bento does not make certain adjustments and run-in to the forward line in the remaining time, Portugal's "forward is weak" There is a good chance that the problem will be exposed again at the European Championships.

Real Madrid's Camuro is Portugal's number one star, having scored more than 40 goals in the league for two consecutive seasons, and despite losing to the more frantic Messi in the race for the Golden Boot, he helped the Galacticos to their first league title in four years.

The Portuguese national team will also have to rely on the performance of the number one star to go far in the European Championships, but it is worth mentioning that the performance of the golden mulo in the national team is far less than that in the club.
