They should sell if players like Marcus Rashford ( He's shown no passion while playing for the club lately. ) Can he go take a look at how Luiz Diaz displays for Liverpool? He seems to have forget when to pass, track back, defend and also make two touch with the ball, him hanging on the ball for too long six to seven touches makes it he'll boring.
Rashford has always been a problem, not only is he selfish he has also started not showing seriousness in playing and even finds it difficult to build teamwork. Against Brentford it was very clear that Rashford only wanted to pass to Bruno and vice versa. So who knows what Rashford problems at Man United are becoming increasingly difficult to control. Erik Ten Hag still gives him confidence to this day, PSG is rumored to be planning to sign Rashford and I don't think Manchester United will just let him go.
His contract with Real Madrid will expire in June, 2024. I heard a rumor, Ancelotti offers him to be apart of Real Madrid coaching staff. If Modric decides to retire in the end of this season, he can accept the offer made by Ancelotti. But if Modric still wants to continue his career as a professional player. Modric must leave Real Madrid since there is no contract extension. There are a rumor of the interest from Saudi teams, they will give Modric a huge salary of Modric wants to play in SPL. Now, it depends on what the decision wants to make by Modric.
I don't think the departure of Modric won't give a serious impact. There are already enough top midfielders to replace Modric's role. Camavinga, Tchouameni, Bellingham, and Valverde are some players who have the same position as Modric. And we must realize that Modric is getting rarely to play full time recently. It indicates that Real Madrid no longer too depends on Modric anymore.
It is true that recently Madrid have started trying to build a game without Modric and it makes sense that what Ancelotti wants to implement is still very much in progress so that when Modric retires, stability can still be maintained. I am also sure that with Madrid young players they are trying to cover Modric position and can be said to be successful. Regarding his future, we would like Modric to be part of the staff because it would be quite helpful for Ancelotti to train his players. But if the decision goes to SPL, everything will still be fine. Unlike Kross, who extended his contract for one more season with Madrid, it's a shame that these two Madrid legends had to part ways.
