It's not a Manchester United curse, it's all about the bad actions of the players. If they did this on purpose, they will be punished themselves, but this also causes big problems for Manchester United. No team wants to be known for such problems. He should be more careful with transfers in the future.
But we can't deny there are so many problems in Manchester United: Greenwood attempted rape, Ronaldo had an internal problem with Ten Hag, Antony is accused attacking his wife, Sancho had an internal problem with Ten Hag. What next? maybe Maguire will never want to leave Manchester United.
Manchester United now is a problematic team lol.
