The players don't have a good chemistry, Ancelotti should being assertive and make the players to respect each other, make Mbappe to feel Real Madrid is his home.
If Mbappe still can't perform, I think we already know who was the one make Mbappe can be like this.
I don't think there is any problem between Real Madrid players, Mbappe is not performing this season and that doesn't mean that he is the reason why Real Madrid lost against Liverpool or why Real Madrid is having a bad performance this season, Real Madrid best players are injured this season and if we look at the players that got injured they are all Real Madrid important players, I know Mbappe don't perform well as the team expects from him but I think he needs time to adapt to the team.
Mbappe is a big player and people will always expect him to play well any time, but I also blame the Real Madrid team and the coach for the team's performance, Real Madrid never played a single season without no a proper striker, Mbappe is not a proper striker that can score with his head and anywhere in the field and I expect Real Madrid to have a good striker that is mature not a player like Endrick, if we look at last season, Real Madrid uses Joselu sometimes and they will win the game because Joselu knows how to score with his head and know how to score goals, I expect Real Madrid to sign more players before the League should start but they did not and I blame the coach for that, the same thing happen for Pep Guardiola too because Pep Guardiola and Ancelotti always think that even if they did not sign players they can still perform well and win trophies every season.
