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.
