What people don't know is that Don Carlo had a knack for diminishing the egos of star players. I have never found Ancelotti to have any problems with his players. This shows Ancelotti's charisma as a coach who is respected by his players. Mbappe will play with Real Madrid next season and that means in my opinion Real Madrid will be the strongest team in the world.
Yep, the players are respect with Ancelotti, if Mbappe becomes selfish and he don't listen to Ancelotti, I believe Ancelotti will don't mind to put him on the bench and replace his position with Endrick.
Mbappe shouldn't bring the culture in PSG to Real Madrid, PSG is really scared to lost Mbappe and not really looking to win every competitions, while Real Madrid goes opposites.
I think the players in Real Madrid will have no other options than to respect them boss Ancelotti this is because he is not a man of many words and he doesn't have issues with his players because he values them so much that's why he doesn't accept his players being so selfish with the ball rather he always advise them to play as a team to get a better and faster results.
Mbappe can not bring his behavior from the PSG team to Real Madrid because he wasn't given any preferential treatment from Real Madrid before coming to the team so I doubt if he will think of being selfish knowing that the team he is involved with right now has some quality players which is in the same level with him
Ancelotti has worked with a number of star players across generations, Mbappe may be the last star player the Italian manager will handle if he decides to retire after his contract ends with Real Madrid. So Ancelotti already has a wealth of experience to make Mbappe obey orders and adapt well with other Real Madrid players. Ancelotti won't let one star player ruin the harmony in the dressing room, and Florentino Perez signed him not for that purpose. Real Madrid before Mbappe arrival managed to achieve success in domestic and European competitions, Mbappe presence should help Real Madrid to maintain this success next season, not the other way around.
