I’ve seen many fans and pundits make this claim. Do you think Manchester United players aren’t playing as well as they can in hope to get Ten Hag sacked. I’ve seen this argument used against Rashford as people since he’s got his new contract he’s just content to get his money and play as well.
Though Hoijund has claimed the players all back Ten Hag still https://www.theguardian.com/football/2023/nov/09/erik-ten-hag-manchester-united-squad-backing-rasmus-hojlund
No they’re all trying (expect the one who’s been expelled from the squad), you can see it when they’re playing. The problem is that some of them aren’t good enough, and others are suffering from Ten Hags tactics.
