There is no doubt about it, the good thing is that in Madrid there is someone with enough hierarchy like Ancelotti who has made himself a Liga player and the UCL player, Something he was looking to consolidate, for me this year has been wonderful for Madrid, also apart from the personal situation of Mbappé I can't deny that he is a good player, that Ancolotti can easily use him as the only striker that Rodrygo, Bellingham and Vinicius can help him, he really will be very good , it's a shame that such a fundamental piece as Kross has left, if he had at least stayed for one more year it would have been perfect, but oh well , now the Question is to find a good Midfielder who can do Things well.
Before the match started, everyone had imagined how Real Madrid would perform when they competed with Mbappe and we also imagined that LaLiga would be dominated by Real Madrid and in the Champions League Real Madrid would be unbeatable.
I agree with you that Mbappe will become even stronger when great midfielders and the help of Vinicius and Rodrygo will provide great attack power that will be unbeatable and difficult to stop.
This season Real Madrid is a little easier to give obstacles to score because the opposing players are quite focused on Vinicius, Rodrygo and Bellingham but after Mbappe's arrival everything will change because Mbappe has very fast running skills.
Real Madrid doesn't need to find a new midfielder because currently Real Madrid's midfielders are very good and Real Madrid seems to only need a backup player like Joselu who has extraordinary talent.
