After Ferguson retired, Manchester Uniteds performance in the Premier League has declined, although this season Mourinho led the Red Devils to win Sir Alexs best performance in the Premier League, but it could not meet Mourinhos appetite. The Portuguese coach is eager to lead Manchester United to more success, so strengthening the squad is a must. Judging from the current lineup of Manchester United, midfielder and defense are the focus of the Reds reinforcement. In these two positions, the reinforcement of the defensive line is undoubtedly more urgent. In Manchester Uniteds Tottenham Cup semi-final, Mourinhos four defenders were Ashley Yang, Valencia, Jones and spin, and the four defenders were Fergusons players to teach Manchester United. After Ferguson, many of the Reds introduced by Manchester United did not come out. It was also evident. Mourinhos dissatisfaction with Fergusons return to Manchester Uniteds defender. Lindlov joined the high price last summer, but it was hard to get the chance to play. Lu Kexiao was abandoned by Mourinho, and Damian was no longer the main force of the team. At the same time, there are reports that Smolin and Jones are also likely to leave this summer. So Manchester United bought a defender at the summer window became a necessity. It is reported that Mourinho is very interested in Seville defender Lang Lai Lai, and Manchester United have also sent scouts to inspect the centre half. Lang Gelai is only 23 years old this year, although he is not very old, but with the Real Madrid Valane with excellent psychological quality, Lang grai speed is not fast, but the position is strong, at the same time the ability to judge excellent, the foot technology ten brilliant, and height 186 centimeters he also has a strong head ball contending ability. If he comes to Lang Lang, he and Barry of Manchester United will become the Red Devils defensive partners in the next ten years. It is worth mentioning that Lang Lai Lai also received the attention of Barcelona some time ago. Barcelona hopes to introduce him to replace Umm Titi who may leave the team. Manchester United will not hang on a tree. Besides Lang Lang, Leicester citys Maguire is also the goal of Manchester United.
