Manchester United's problem is not just Onana, it is deep. In their last two games, it was Bayindir's blunder that gave Arsenal all three points. In their match against Fulham, they didn't play well and Fernandez failed to convert a penalty kick that would have been crucial to them sealing a win, and yesterday they were knocked out of the EFL Cup by a fourth-division side. Even Amorim admitted after the game that changing the whole 22 players won't solve the problem. It looks like he doesn't even know what to do anymore.
