'Slightly baffling' - Gary Lineker admits he 'really worries' about Ruben Amorim's treatment of Man Utd star

Mainoo, who starred for England during Euro 2024, has seen his progress stall since Amorim’s arrival at Old Trafford. The 19-year-old has yet to start a Premier League game this season despite United’s injury issues in midfield. His frustration even led him to request a loan move in the summer, but the club blocked any potential exit.

Speaking on The Rest is Football podcast, Lineker said: "I don’t think he’s going to change his system now. He’s been very stubborn so far, why change now?

"It really worries me the way Kobbie Mainoo has been kind of dismissed. Such an incredible, young talent, a local boy as well doing really well.

"I thought when he came on he did really quite well. I don’t get it, I don’t know if there’s something we don’t know about but it’s slightly baffling to me."

Mainoo was expected to build on his breakout season under Erik ten Hag, but finds himself on the fringes under Amorim. Manchester United’s struggles in midfield have only made the lack of opportunities more puzzling. If the situation continues, questions will grow over whether United are stalling the progress of one of their brightest academy products.

Manchester United face Chelsea next in the Premier League, with Amorim under pressure to shake things up. Mainoo could once again be left waiting for a starting chance unless the manager reconsiders.
