With Kylian Mbappe, Coach Ancelotti can arrange many different formations and all possess terrible destructive power. Mbappe's position in Real's attack is the story I'm interested in after the French striker debuted at the Bernabeu. Honestly, it's not difficult to put Mbappe in the lineup. He will integrate into the team. The important thing is that Mbappe has enough talent and dedication for the team. Coach Ancelotti will use Kylian Mbappe as a trump card to change his tactics unpredictably in each match.
I remember Anceloti been Interviewed on Obi Michael, ex Chelsea midfielder podcast and when he asked Anceloti where he will be playing Mbape and he responded forward but didn't indicate which particular position in the forward and he made examples of how Vinicious, Rodrigo, and Bellingham are Versatile players which he used on any place that he want and they perform excellently. I think that's what he is going to be doing with Mbape coming matches.
I too believe on Anceloti and he is not the kind of person that do too much, if it's not going to favour him, he will know from onset, Mbape is a big project for Real Madrid and he is going to deliver until 2026 which I think he might want to retire possibly. I'm not sure if he is ever going to work elsewhere after Real Madrid.
We just need to wait for how Madrid's formation will be next season because after all Madrid is always identical to 3 strikers even though last season there was a difference where Ancelotti was more interested in playing only 2 strikers as an option because indeed last season Ancelotti was more inclined to play Jude in the second striker position.
But looking at the current conditions, I think Ancelotti will return to the formation that Madrid has always done where 4-3-3 is always an option.
The scheme is that 3 players in defense can be placed anyone although I prefer to see Jude, Tchouameni and Valverde as starters and Camavinga, Modric and Arda as coatings there. The 3 strikers up front would be Vini, Mbappe and Rodrygo with Brahmi and Endric as options.
This is still the most likely situation especially with the nature of Tchouameni and Camavinga who are flexible enough that Ancelotti will not feel bothered to maximize the midfield and defense so that the focus on attack with 3 strikers is still very possible to happen.
