Many reporters and professionals have asked Ye Qiu the same question, why would he choose to abandon the 433 tactics he used at Ajax for four years and are more familiar with after coming to Chelsea, and instead adopt 43L tactics?

For this question, Ye Qiu's answer has always been that different tactics are adopted according to different types of players, but in fact, he himself knows very well that there is a deeper factor in this, that is, the defects of 433.

I believe that in the previous life, many fans who watched Mourinho's 43 at Chelsea and saw Mourinho's 43 at Inter Milan plus 43 at the peak of Barcelona will naturally feel that 433 should be the strongest tactic in that era.

It is undeniable that 433 does have a very good side of him, and that is freedom.

If you only look at Mourinho's 43, the most intuitive impression of everyone should be the pressing defense and sharp and fast counterattack.

Jose Mourinho is a smart man, he has always been able to master the way to lead the team to consistent results in the shortest possible time, but at the tactical level, he does still have a big flaw, he did not have enough knowledge of running off the ball during his time at Chelsea, in order to play the attacking ability of the winger tactics, then he can only use the meat grinder midfield, using physical energy to run and cover.

The flaw of the meat grinder midfield is that it is too tough, it is more dependent on physical strength, and it is often easy to be at a disadvantage when encountering teams with more control ability, so Chelsea always have one less person when they meet Barcelona.

If you only look at Barcelona's 433 tactics, what you will see is the pressing attack and the excellent off-ball running and passing and receiving system, of course, in the eyes of ordinary fans, they may not see this, they will intuitively watch the game and sigh that Barcelona's players play so freely, they can cooperate wherever they go, and play how they want.

If purely from a tactical point of view, Barcelona's 433 is indeed more tactically valuable than Mourinho's 433, which relies more on the physical fitness of the players than on the tactics themselves, but Barcelona's tactics also have a problem, that is, the lack of vertical attacking ability.

It must be explained here that 44 is the most standard and balanced tactic among all tactics, and the distance between players is kept just right, but if it becomes 43, the distance between players is much more than that of 44, whether it is a horizontal or vertical comparison, which is the price to pay for the mobility of players.

If you want players to be fluid and run freely, then you have to leave room for them to run, don't you?

Especially for the distance between fullbacks and wingers, it has been maintained at more than 25 meters for a long time, and the distance between wingers and centers is about 10 meters more than that in the 44 double striker tactics, which is why Ajax has completely reduced the power of 433 and the strength of the team has declined rapidly after taking a group of outstanding wing players.

In the past, many fans accused Barcelona of attacking too many crosses, which was due to the need for the team's possession system, but in fact, part of the factor was the lack of a consistent midfield receiver.

If you look closely at Barcelona's tactics, it is not difficult to find that almost all of Barcelona's ball advancement is to find the wing, advance from the side to the front, and then go back to the middle through the wide players, such as the very famous Ronaldinho and Giuli after cutting inside the two wings.

Why is this happening? The reason is simple, Eto'o is not a qualified lone striker in the 433 tactic, and even if he goes to Inter Milan, Mourinho uses him on the wing.

It must be clarified here that just because there are more goals does not mean that he is suitable

When a team has a strong and consistent variety of ball progress, which is the so-called ability to create chances, even if there is an amateur striker in front of him, he can still score a lot of goals, but it does not mean that he is suitable for the team's tactics.

Eto'o's biggest weakness is that he lacks the ability to match the two wings, and his ability to carry the ball in the middle of the box is also slightly lacking, so when Inter Milan was in the middle of the field, the stable point of possession in the middle of the field was Diego Milito.

Samuel Eto'o is undoubtedly a very good top striker, and he also has a strong tactical adaptability, being able to play as a double striker and a single striker, but that doesn't mean he can be the best player in different tactics, and any player can only get the most out of the tactics that suit him best.

Because of Eto'o's weakness, or insufficiency, it is difficult for Barcelona to pass directly to Eto'o, and more can only go to the side, so there will inevitably be more horizontal passes, plus in order to stabilize the ball possession, so there is Barcelona's much-criticized mechanical pass.

Pep Guardiola is also aware of this, so he wants to bring in Ibrahimovic, and the Swedish striker's ability to hold the ball up front is absolutely not in doubt, but he seems to be a little out of tune with Barcelona's tactical system and requirements.

That is to say, with Barcelona's technical skills and team awareness, and Eto'o's excellent individual ability, there are still shortcomings and deficiencies in their use of 433.

Learn from Mourinho, play defensive counter-attacks, play the tactics of fast forward in the frontcourt, and then complete the coverage with a meat grinder midfield.

Think about it again, did Alex Ferguson's Manchester United also use this tactical style when they won the Champions League?

Think about it again, why did Wenger hold on to 44 and not let go?

In the case that the player's technical ability, running ability and other qualities do not meet the requirements, rashly adopting 433 tactics is self-defeating, so for Ye Qiu, only when Fabregas, Messi, Ribery, Van Persie and other players mature and can take charge of themselves, he will turn to 43 to maximize the team's attacking power.

It can be said that there are not many people in today's football world who are more familiar with and understand 433 than Ye Qiu, because this set of tactics is his housekeeping skill, and he has also studied the experience and experience of many famous coaches in the world on 433 tactics, so he clearly knows the weaknesses and shortcomings of the current Barcelona team.

Rijkaard's team is full of problems almost everywhere in Ye Qiu's eyes.

Eto'o as a single striker and the left and right wings are not enough, let alone Iniesta and Giuli form a wing, the former is a little slower, the technique is very good, and the creativity is enough, but behind him are Abidal and Van Bronckhorst, and behind Giuli is Belletti, and there is a big hole between the winger and the fullback.

Barcelona's midfielders are Xavi, Motta and Marquez, and the two central defenders are Edmilson and Puyol, the thickness of the midfield is relatively weak, and Barcelona advocates possession and counter-attack, which has a premise.

Barcelona are the most dangerous when they can get a continuous stream of high-speed passes and players can effectively weave back and forth to run, as their passing penetration will tear apart any defence.

Because of this, when Barcelona encounters those teams in La Liga that are not defensively strong, not pressing, and unwilling to defend and counterattack, they almost don't feel the pressure of defense, which is also the reason why Barcelona can perform well this season, but when Rijkaard meets Ye Qiu's Chelsea, his 433 tactics fall apart.

Chelsea are still playing a 3L strategy, with Edwin van der Sar in goal, Patrice Evra, Cannavaro, John Terry and McCone at the back, Deco and Makelele at the back, Ronaldinho, Frank Lampard and Wayne Rooney up front, and Drogba as the lone striker.

Out of confidence in his team, Ye Qiu announced his starting list for the Camp Nou Stadium early after playing the FA Cup match in Newcastle.

The first is not to grab possession with Barcelona, but do their best to press Barcelona on the ball, and once they get the ball, they don't stop the ball and go straight to the front, or Ronaldinho and Rooney on the wing, or Drogba and Lampard.

Ye Qiu knows very well that in front of Barcelona's defense, Chelsea's frontcourt players have a certain advantage in taking the ball, even if it is the young Rooney, so Chelsea can boldly pass forward, there are many receiving points in front, and quickly pass to the front, which can maximize the effect of Barcelona's counter-robbery and hit the enthusiasm of the opponent.

Second, once they have the ball, the full-backs move forward quickly, attacking the weakness between the opposing wingers and full-backs in the shortest possible time, taking advantage of the numerical advantage, as well as repeated attacks and breakthroughs, to break down Barcelona's defense from the wings.

Therefore, in this game, Ronaldinho and Evra, Rooney and McConn, almost completely broke Barcelona's two wings into a sieve, if it were not for Drogba's lack of ability to seize opportunities, Barcelona conceded at least 5 goals in this game.

With the first and second points, Chelsea naturally gained the advantage on the field, using Barcelona's half as the main battlefield in the game, and then suppressed and dismantled Barcelona's tactics.

In fact, the first leg of the Champions League round of 16 knockout match at the Camp Nou has lost suspense since the 3rd minute, Ronaldinho received a pass along the left side of the backfield, quickly formed a breakthrough, after getting rid of Belletti, got rid of Puyolneche in the left corner of the penalty area, and faced the attacking Valdés after entering the penalty area, and directly kicked a calm shot.

The ball crosses an arc and hits the right net inside the goal, 0

After that, Chelsea continued to take advantage of the stable ball in the frontcourt, giving full play to the characteristics of the side attack, attacking the weakness and deficiencies of Barcelona's side defense, and attacking and suppressing Barcelona's side again and again, but never found a chance to break through Barcelona's goal again.

Until the first minute of the second half, after Ronaldinho retreated to receive the ball, he directly transferred a wide range of diagonal passes, Rooney quickly inserted the ball and advanced to the right side of the penalty area, and made a quick stop cross, Drogba Yu disturbed the attention of Puyol and Edmilson, and Lampard scored with a header from close range, 0

It was also the only two goals of the game as Chelsea beat Barcelona 0 away

At the moment of the final whistle, the entire Camp Nou stadium was in complete despair

If last season's Barcelona brought bitterness and tears to Barcelona fans, then this season's performance has improved, Rijkaard boldly promoted Andres Iniesta and brought in a number of players to further strengthen the overall strength of the team and allow Barcelona to perform in La Liga.

But when Barcelona met Chelsea, who is known as the strongest in Europe, they really felt that there was a huge gap between themselves and the top teams, not only in terms of strength, but also in terms of tactics.

Cruyff, the godfather of Barcelona who was the guest commentator of this game, summed it up and believed that it was difficult for Barcelona to make a difference in the Champions League, and Rijkaard could put all his energy into the league next.

"I said before the game that no one knows the essence of 433 tactics better than Ye Qiu, he overturned the traditional 43 of Ajax and improved it, making this set of tactics more suitable for the trend of modern football, he is very aware of the problems that may arise with the use of 433, Rijkaard does not have any advantage in front of Ye Qiu."

Cruyff made no secret of his disappointment at Barcelona's performance, even though he knew it was more due to Chelsea's excellent performance.

'When we know very well that the opponent is the best at pressing and controlling the tempo, we shouldn't show the timid side in those two areas, we should counter-press and we should fight Chelsea to control the tempo, because that's the only way we have a chance to win, but at this point, the team did a terrible job.

'I saw that we didn't put in the determination to fight for the rhythm, but it was Chelsea who were bold enough to press and press from the start and managed to score, and our weaknesses on the flanks were exposed, and Rijkaard's side were a bit like Ajax before Ye Qiu took over, very similar.

This also sounds like Cruyff is hinting and beating Rijkaard, completely failing to learn the experience and lessons due from Ye Qiu's transformation of Ajax, and still blindly using the wing tactics he is familiar with.

"The other thing is that the team's tactical adaptability is very bad, when we see Ronaldinho and Patrice Evra breaking through Belletti again and again, Rooney and McCone defending through our left side again and again, we should have made changes and adjustments, but the team did not change in the slightest at this point, and the goals conceded in the second half were still started from the wings."

And the most final, Cruyff also summed up the game against both sides, thinking that Barcelona lost because of the lack of quality.

'Chelsea are a team that is still figuring out their style but already has a very high quality game, and they know exactly what they are and what they should do all the time, which makes their every move full of purpose, ideas and rules, which is certainly something for all teams to learn from.

'I don't usually praise a team lightly, but now I want to say that Ye Qiu and his Chelsea will have a chance to reach the top of their game, they are the biggest favourites in the Champions League this season, and I can't think of any team that can compete with this Chelsea team, no one'

Ye Qiu also thanked Cruyff for receiving the praise from Cruyff in his post-match press conference, but said Chelsea were not at their best.

"A lot of people say we're strong, but actually, I know in my own mind that we still have a lot of potential to tap into, and I believe that as more and more young players emerge, as the team chemistry gets better and better, we will get stronger and stronger as a whole, and neither I nor my players want to hide our desire and pursuit of all the titles."

"Yes, we've made a lot of records and history this season, but no one gets too much and no one gets tired of accolades and victories, at least I didn't perceive that, so we're going to keep going all out and fight for every title and win every game."

"I know that there are a lot of strong competitors in Europe, but I believe that as long as we give it our all, no one will be able to stop us from moving forward."

Ye Qiu's comments at the post-match press conference were also widely reported by the media, and were regarded as Chelsea's passionate declaration of the Quadruple this season, and Chelsea responded to and supported the manager's ambitions.

William Hill minimized Chelsea's odds to advance after the first leg, and even so, the vast majority of bettors chose Chelsea, believing that with the Blues' unstoppable momentum at Camp Nou, Barcelona would not be able to stop the Premier League giants.

Even in the odds of winning the championship, William Hill also offered Chelsea an ultra-low odds of 45 odds, which also proves that the vast majority of fans are optimistic about Chelsea, followed by Real Madrid and AC Milan, the former is a l odds and the latter is a l odds The odds are very different from Chelsea.

Also in the round of 16, Chelsea won Barcelona steadily, Arsenal lost 3 away to Bayern Munich, Liverpool defeated Bayer Leverkusen at home, and Manchester United lost 0l at home to AC Milan.

The Gunners' tragedy has clearly dragged down the league, as they drew at Saints Southampton in the Premier League round P on Sunday, and Arsenal managed to close the gap to 14 as Chelsea were to play the Carabao Cup final

Manchester United beat Portsmouth to catch up with Arsenal on points, the two teams are tied 14 points behind Chelsea, and because Everton also won, Liverpool, who were also postponed in the P round, fell to the top of the league

On the day of the month, the Millennium Stadium in Cardiff, at 15 o'clock in the afternoon, the League Cup final kicked off on time
