I think Mbappé is a player who is open to innovation. I don't think I need to say that he is also very talented. Ancelotti can turn him into very good positions. He can give him new positions. Just like Bellingham. Jude Bellingham has adapted very well to the number 10 position. Mbappé can experience something similar
I also have no doubts about Ancelotti's ability to change some players' positions into unusual lines and that has indeed happened to several players before at Real Madrid and it is possible that it could happen again to Mbappé. This season, Real Madrid actually has a fairly complete squad and is also very capable of competing in every competition, but for now, several players from Real Madrid are undergoing their recovery period, such as Jude Bellingham who is still recovering from an injury.
We will see significant difference in the Real Madrid squad for the upcoming UCL match, from the line-up of players and also the tactics of the game will definitely be very different from them playing for the La Liga competition because Ancelotti will make difference for the forward position which currently has Mbappe.
But for the future I believe that Ancelotti will be able to show how great he is in handling Real Madrid even though he has to lose one of his main players Bellingham who usually fills the center position.
Injury suffered by Bellingham is estimated to take up to amonth to recover and of course shows that in several matches Bellingham will be absent including for their first UCL match later.
