Nothing seems to be working right for United. First thing Manchester United should do is replace Harry Maguire. Maguire has been a disaster for Manchester United thus far, he is not deserving of the post as captain of the team. Just probably because he is a English player because it really doesn't make sense. A Christiano Ronaldo should be captain. He has done it all, the younger players will listen to him.
It's irreplaceable for now but it will probably happen next season.
Maguire's performance is really bad for the high price given. he always does things that are unnecessary in my opinion and this makes the team feel at a disadvantage.
It doesn't matter what even in their last 2 matches in EPL and CL I think we can see the blunders he made are always a loss for the team because with the mistakes he made Manchester United would always concede the ball
