Considering that Grimsby is a fourth-division team, in my opinion, any Manchester United squad should have beaten them. But they couldn’t even get past the first round of the Cup, and that’s terrible. I looked at the lineups, Amorim played a demotivated Onana, with whom he has a conflict and who is planning to leave the team before the end of summer. I think that was a very wrong decision. Yes, I agree that it shows what was already clear, it seems to me that Amorim will leave the team soon.
I don't think there's any point in changing the coach again in the middle of the season. Even if it's a lost season, well, let it be that way. We need to let Amorim work until the end, maybe his plan will start to be realized? I don't really believe in it, but it won't be worse than last season. United's next game is at home to Burnley and if they don't take 3 points here (bookies are pricing this outcome at 1.37) then I just don't know what to expect next.
