Manchester United has enough players in the team but those players are currently performing very poorly. If a new coach joins the team and implements new strategies and tactics, hopefully the team will return to its previous performance.
I think only a few players, we can't rule out players who have work hard to keep Manchester United at the top of the standings like Marcus Rashford for example, and there are a few more players.
If look at Manchester United's overall gains in the EPL, they are currently still pretty good and we can see Man Utd are still dominate the third and fourth positions in the EPL.
I might be a little curious about that statement, because basically the new coach Erik ten Hag has done as well as he can this season and the result is that Manchester United are in the top four. Indeed, recently Manchester United's performance and match results have dropped a bit, but we also can't make a statement about Erik ten Hag not doing well.
Because after all, this is Erik ten Hag's first season in and coaching a team in the Premier League, but Erik ten Hag can work well. So yes, with Manchester United still having a great chance of being able to maintain its position in the top four, then of course Erik ten Hag has at least had some success in his first season at Manchester United.
