I don't think that it's because Manchester United was a big team that was why he was not able to deliver the truth is that any player coming to Manchester United will not play at his best because the environment in united is not a good one that players can do well
Yes, Manchester United's team atmosphere is not very good now. I haven't even seen them in a very good position (although they may have been in a good position in history). Manchester United's big problem is match planning and the players not being able to play their game. I still don't have a specific answer as to why they can't play well. But when I see a good player going to Manchester United and not being able to play well, it seems suspicious to me. It is not necessary to be world class to play well, but rather to be world class you need to play well. So before being world class, a player has to play well, but this is missing from them.
Everything about the Manchester United team is just old glory they have nothing good now about the team cause they haven't achieved anything new since Alex Ferguson let the team they are not doing well in the league and winning games was a very big problem for them because they have no serious players in the team aside Bruno Fernandes. Good players get to the team and become infected by the performance of other players there that is why nothing is working in the team.
