I agree with you, for me Ancelotti is one of the best coaches that Madrid has ever had, sometimes I don't quite understand what he wants to do because he comes out with the wrong strategy or formation and he hasn't solved Viní's position with Mbappe either, that's something that needs to be solved soon, I would like them to give more minutes to Arda Guller who is playing very well, however he may have stumbled in some games, like he did with Barcelona, which really was not Madrid's day, even the league gives revenge and next time it must be prepared.
Regarding the positions of Vini and Mbappe, it is indeed a difficult thing because both are good players but the problem is that they operate in the same position, which means that one of the players must be sacrificed to be rotated and occupy another position. And coincidentally the position needed is a center forward and Mbappe was shifted to center forward and the results have not been very satisfactory. He tried to experiment, but so far what he did has not been very successful. Actually I don't agree if the coach experiments in the middle of the competition, but I can understand that there are not many options for Ancelotti so he has to dare to make decisions, which currently do not look impressive, even tend to be disappointing.
