Okay, 5 players (Rasford, Antony, Garnacho, Sancho and Malacia) of Manchester United asked to leave. This is such a good news for MU because they don't need to put more effort in order to sell them. However, this news is so late. This should happen like two years ago in order to minimize their financial lose.
They have to accept the financial lose from selling them all, then focus on how to rebuild the club back from the scratch.
Man Utd inevitably have to accept this condition as a consequence of their past mistakes and if they continue to retain players who are no longer ambitious to play, then retaining them could hinder their performance next season. Man Utd is currently in a phase where revolutionizing the squad is a must, the starting point must be restarted to restore Man Utd's aura. I heard that Sancho is in demand by Serie A clubs, this sale must be done immediately to at least minimize losses.
