If we look at his goal, Mbappe to Real Madrid is not just about one trophy, but more about many trophies because he himself knows that Real Madrid has enough strength to hope for that which has been proven through the 2024 UEFA Super Cup. And for the next target is the La Liga trophy accompanied by the Copa Del Rey trophy and also a trophy that is quite prestigious, namely the Champions League trophy which during his time defending PSG Mbappe has never lifted the trophy, but he could get it through Real Madrid.
It seems to me that given that Real has won all these titles in recent years without Mbappe quite easily, Mbappe has a more difficult task than simply winning titles (even the most prestigious ones) with Real. He needs to make a contribution to the team's success that would make him stand out from the rest, to rise to or surpass Ronaldo's level. Otherwise, people will troll him by saying that his titles are more a consequence of the fact that he moved to Real than that he is truly worthy of them.
it's much easier for mbappe to win the championship and trophies we still haven't reached the point where there is an antagonist like in the ronaldo era, let's say that there was a certain messi who was there and won and also greatly stimulating everyone to grow while Now there's only Real Madrid, it's easy to win like that!
