Former Premier League star, Danny Murphy has slammed Manchester United over a move to sell star player; Kobbie Mainoo.
He wants the club's boss, Ruben Amorim, to make sure such a deal never happened.
He said the manager should continue with the attacking midfielder, saying the club should not look at profit, as they will soon need to sign a player as valuable as him.
Murphy is of the opinion that Amorim needed to trust the player with the defensive role and let him play deeper.
It would be a big mistake for the Red Devils to allow the player to leave Old Trafford, according to Murphy.
He wrote on Daily Mail, “I don't see what Amorim sees when it comes to Mainoo. I think Mainoo is more than capable of playing that defensive role, he just needs some help, leadership and guidance around him.
“I also don't think he should be pigeon-holed into being one style of midfielder because there is so much variation to his play.
“I understand the rumors around him and Alejandro Garnacho needing to be sold for PSR reasons but the equation is simple: are United blessed with an abundance of talented midfielders? No.
“Casemiro and Christian Eriksen are coming to the end of their careers. They let Scott McTominay go. He [Mainoo] is exactly the type of player United would be looking to sign if they didn't have him already.
“Even if they sold him for pure profit on the balance sheet, they will have to spend just as much, if not more, to replace his talent.
“Mainoo and Garnacho are two talented, hungry players capable of having a big impact for United over the next five years or more, whether that's under Amorim or any other manager. If I was Amorim, I would be talking to Mainoo, talking to my bosses, and making sure he stayed.
“I would still be shocked to see him leave in the summer. His performance the other night will have provoked a lot of conversations as to why he has not been playing,” he added.
Mainoo scored a late goal (120′) in the 7-6 aggregate win over Lyon last week (second leg on April 17) to help Manchester United qualify for the UEFA Europa League semifinals. The goal was the equalizer before Harry Maguire scored in injury time (120+1′).
