Even though it looks selfish in terms of every match, I think it's fine to rely on Kylian Mbappe because he can indeed be superior to other players with very strong performance and the tactics that are always used are very precise.
But I understand that Ancelotti is thinking again about getting Kylian Mbappe because of fears he will change strategy which will end in conflict with other players at his own club.
Kylian Mbappe is indeed a very talented player but I don't like it when he is too arrogant like he wants to excel himself.
I am agree with that because indeed Mbappe can always play well and has points when the opportunity arises.
If it weren't for Mbappe being a great player with quite good attacking skills, it would have been certain that PSG would have released Mbappe and sold it to another club.
Ancelotti is an experienced coach so it is impossible for him to worry that Mbappe's arrival could change strategy and lead to conflicts with other players, there must be a way that Ancelotti uses to make Mbappe have a good game and be able to collaborate with other players.
I also personally think that if Mbappe leaves PSG and joins another team, then PSG will break the basic structure of the team. Because Kylian Mbappe is one of the best players in the attack, it will be very difficult for the team coach to fill that need by replacing him with another player.
