I agree with you on that statement, because I am one of those who believe that when Madrid is losing it is because they do not have Mbappé up front. For me, the striker who has to get the most out of it Now is Mbappé Of course , Vinicius, Rodry and Bellinham help, but the one with the best goal-scoring instinct is undoubtedly Mbappé, The good thing about Madrid is that it has so many variants that with any Madrid player a dream team comes out and any Combination is good , but you have to be more accurate and win the points.
Real Madrid won La Liga and Champions League last season without Mbappe and this player only came to their club this summer, and had several matches for them. It's important to remind a fact that Mbappe struggled in early matches for Real Madrid too. He is a super star player and will be more important with Real Madrid with time, but at this moment, in his early adoption there, he is not too much important with them. Attributing a loss because of Mbappe, is not closely to actual reason.
Euro 2024 and Coppa America 2024 in this summer actually affected many star players who returned to their clubs with injuries or exhausted bodies and were not too ready for a new season.
One a big problem of Madrid now is inconsistent to hold their performance along the match. The team sometime appears dominant, but then experienced a significant decline their performance. Ancelotti must pay attention to this problem. We don't know what is problem between player, or something happen with anceloti strategy
Real Madrid have many star players who were called for two big tournaments in the summer, Euro 2024 and Coppa America 2024, and they got effects from these tournaments. Jude Bellingham got an injury after Euro 2024 and only returned to their squad recent matches. The appearance of Mbappe in Madrid, causes internal conflicts among their attacking star players like Vinicius and Rodrygo, this is a big issue needs to be handled cleverly by Ancelotti.
Mbappe has to be more friendly with his team mates like Vinicius and Rodrgyo, because showing his high ego only makes things worse and harms his connections with these attacking team mates. It will not be helpful for his career in Real Madrid in long term.
