Real Madrid can bring in almost all of the world's top attackers, but the introduction of reinforcements at the back is very problematic. These two seasons have been one of the best defensively in the last three decades, with Marcelo, Tsuba, Raphael Varane and Carvajal among the best in Europe, but that's after adding to the attacking prowess. In terms of defensive ability alone, it can only be regarded as a second-class level, and there is still a big gap from the top.

Leaving aside the two wings, let's talk about the centre-backs. Shui Ye's goalscoring ability is comparable to that of a good center forward, but his entire career has been marked by recklessness and the trouble of selecting positions, the former earning him a far more than average number of red cards, and the latter frequently preventing him from reading the game correctly in critical moments, resulting in serious misplacement. In addition, the Real Madrid captain is not young, his peak will soon pass, once his physical fitness declines, his previous superhuman ability is likely to cease to exist.

Raphael Varane can be regarded as the leader of the new generation of centre-backs in terms of defensive ability and awareness, but since moving to Real Madrid at the age of 18, his development has not met the expectations of him, you must know that he was called the next Laurent Blanc and Marcel Desailly. The 23-year-old Varane has not only failed to show his superhuman strength against his peers Aymeric Laporte, Daniele Rugani and Marquinhos, but is in danger of being overtaken by rising stars such as Alessio Romagnoli due to his high injury constitution. Injuries for months have seriously affected his career, and Van Basten and Ronaldo are both immortal talents, but unfortunately they have both fallen from the altar due to injuries, and Varane is very likely to repeat their mistakes.

Needless to say, the ability of the veteran Pepe is always short-circuited, coupled with the characteristics of the above two shortcomings, he has not been able to get an evaluation that matches his ability. Although the warrior monk who has come to the end of his career has gradually reined in the madness and frizziness of his youth with the increase of age, it is a pity that the years are not forgiving, and the decline in physical fitness such as speed and bounce has made him lose the capital of being the main force in the top giants, and the day of leaving Real Madrid seems to be predictable.

Fortunately, Real Madrid's first team introduced young central defender Vallejo from Zaragoza in the summer of 15, this young player born in January 97 has very amazing potential, and his mental attributes are so strong that if he can grow up healthily, he is very likely to take over the banner of the water master and guard the city of Real Madrid for more than ten years in the future.

But only one of the two centre-backs is not a reliable one. Among the remaining players, the 26-year-old Nacho has reached the peak of his ability, has no potential, and can only play a substitute role in the team at his current level; Another hopeful, Diego Llorente, has been on loan and has not proven himself in a strong team. Just in case, Real Madrid need to prepare an extra young centre-back to join the future construction, and the answer given by Li Mudi is Mele.

In terms of potential, Sporting Gijón's academy graduate Melle is very similar to Diego Llorente, both have the potential to become a first-class centre-back, and the former is obviously more precocious, and has gradually appeared in the team's main position in the middle of this season. If the purchase is made in the summer in a few months' time, it is estimated that it will be difficult to impress the management of Sporting Gijón without 20 million euros, and this winter transfer window will be the last chance to win him for a low price. But even so, the other party made an offer of up to 16 million, a price that the Real Madrid management would never agree to. After 20 days of revolving, the price reached 12 million and could no longer be reduced. Seeing that the transfer deadline was approaching, Li Mudi did not want to miss this great opportunity to strengthen the team's future strength, so he reluctantly proposed a loan to the opposing Odegaard, which made Sporting Gijón, who just lacked the core of the frontcourt, moved, made concessions on the price, and finally completed the deal before the deadline.

Melle stayed with his parent club in the second half of the season and will not play for Moody's Castilla even if he comes to Real Madrid in the summer. For the benefits that he could not enjoy, Li Mudi paid a huge price for the loss of the core of the midfield for the public, and this great spirit of harming himself and others touched Zizu and the club's senior management, so that in the future, when he bought and loaned players from Real Madrid, he almost never encountered the difficulties of human factors, and it can be regarded as a good person with good rewards. In fact, this is all a routine played by Li Mudi, how can others who don't have a gold finger understand!

After some adjustments, Castilla's original frontcourt only left Toro and Álvaro, the original coach's main striker Mbappe because he was also valued by Zizou and followed the first team for a long time, but fortunately, Mariano conquered everyone with an outstanding performance and became the team's attacker. Odegaard's position can be handed to Febas, the 20-year-old midfielder who has improved rapidly in recent months and has the potential to become an all-round attacking and defensive central midfielder. Kuchi will take the place behind the striker, and Enzo's completely different style of play will be the secret to the team's success in the coming months; The most worrying thing is the left winger, Mbappe can only be temporarily supported for a while, and then Lin Liangming or Cedres, who can take care of the left side, needs to grow up as soon as possible.

On Thursday 4 February, at 19:00, Castilla hosted Lynns for the first leg of the quarter-finals of the Fed Cup.

Castilla's starting line-up for this game: goalkeeper Abad, right wing-back Dani, central defenders Linhardt and Manu, left-back Rodriguez, central midfielders Peperu and Ganfonina, right winger Cedras, left winger Lin Liangming, shadow forward Kuchi, striker Mbappe.

Lynnes are currently 11th in Group B4 of La Liga, which is considered a weaker team in the quarterfinals. The formation of this game is 4-4-1-1, and the quality of the players on the field is very average, only the 33-year-old veteran striker Kepi has extremely high shooting skills and runs off the ball, and needs to focus on defense. In addition, the two central midfielders, Canario and Zico, work together very well and are also the core players of the visiting team.

After the opening, the home team wanted to control the ball first and mobilize the opponent's defense line to find the flaws, but who knew that there were frequent mistakes as soon as they came up, and there was no tacit understanding at all in the passing and running cooperation. Just when the players were still looking for a feeling for each other, Lynnes suddenly made a move, seized a mistake from Gamponina's return pass, and Canario intercepted the ball and dribbled directly to the top of the penalty area for a powerful shot. Abad's vision was disturbed by Linhardt, who was on guard, and he was a little slow to react, but he barely managed to save the ball. Kepi, who was following him, used his keen killer nose to quickly spot the rebound and get one position ahead of Manu in front of goal, nudging the ball into the empty net. 0-1, six minutes into the opening game, the visiting Lynnes took the lead.

An inexplicable mistake led to the loss of the goal, which was very annoying to everyone, and after the restart, Castilla began to attack wildly, but the cooperation between them was still not effective, and many good chances were wasted. It wasn't until the thirtieth minute that a simple cross from the right side was played, Cedres' cross was squared by Mbappe in the middle, and a strong header from close range caused the opponent's goalkeeper to save the ball, and the French striker, who had an excellent second reaction, fell to the ground and stabbed the ball immediately after landing, touching the ball into the goal, and the score was leveled.

It was the last chance of the first half for both sides, and the home side continued to be plagued by mistakes and struggled to find their way into the opposition's danger zone. Lynnes, on the other hand, focused more on defending after scoring an away goal and failed to capitalise on the opposition's mistakes to create any good chances. With a score of 1-1, both teams ushered in the whistle of halftime.

In the home team's lounge, Li Mudi briefly commented on the team's mistakes in the first half, asking the players to focus on simple tactics first, and abandon the offensive routines that require complex running. At the same time, he squeezed Kepi's living space on the defensive end, and someone had to follow him closely at all times, so as not to let him get a chance to touch the ball comfortably.

At the start of the second half, in the face of a defensive formation with deep retreat, Castilla abandoned the previous play that required multiple players to play the ball, and frequently used a style of play that required less team understanding, such as one-twos, wide crosses and individual breakaways. Mbappe, who was at the front, was not as good as Mariano in his ability to compete for headers, but his combination of speed and power could still cause great problems for opponents, and Kutch's dribbling at the edge of the penalty area also won the team many free-kick opportunities, but unfortunately failed to take them.

In the 58th minute, Li Mudi replaced the inactive Lin Liangming with the striker Rivero, who was transferred from the U19s, and Mbappe came to the left side. The substitution worked wonders immediately, in the 63rd minute, left-back Rodriguez sent in a low cross, both players in the middle failed to touch the ball, and Cedeles, who was inserted on the right, received the ball on the sideline of the penalty area and kicked it back directly to the ground. The ball slid lightning past the toes of several players to the back post, and the unguarded Rivero slammed the ball into the back of the door with ease. At 2-1, the home team overtook the score.

After taking the lead, Castilla continued to work hard and extended their advantage to two goals with a brilliant long-range strike from Kylian Mbappe in the 71st minute.

As the home fans celebrated the impending victory, Lynnes launched a blitzkrieg after kick-off, with Canario's pass flicked back to substitute Espinal, whose powerful shot from 25 out was blocked by centre-back Manu with his legs. Canario's corner from the right was flicked into the far corner by defender Joe at the far post, where Peperu, who was marking the opposition, scrambled to clear the ball with his own goal. 3-2, the away team narrowed the gap in the score in an instant, and it also made the full fans who were still elated just now hug their heads and sigh.

Fortunately, Li Mudi turned on the hair dryer and intimate brother mode in time, so that the players calmed down in a short time, continued to attack the opponent's goal with a normal mentality, and in the 89th minute, Cederes received a pass from Mbappe and pushed the shot, fixing the score at 4-2. A two-goal lead in the first leg was an acceptable result, but two away goals were not good news, and the situation became delicate.

Without waiting for the team to sum up the various mistakes in this game, Castilla had to go north to the Basque Country to challenge the opponent of the 24th round of the league, Leoia. Facing the 16th-placed underdogs, Li Mudi's team was once again beaten twice by the opponent, only to get the expected three points 3-2 thanks to goals from Mbappe, Mariano and Muñoz. For a while, a large number of problems occurred in Castile, which had an updated lineup, and became a hot event in the La B League, and Li Muddy once again stood on the cusp.
