In an interview with AS, Casemiro said: "It has been difficult for Mbappe? Yes, but he is already established and will give you 40 goals a year. The youngsters, like Rodrygo, Militao or Fede, who I admire a lot for the way they play and give their all, know how to wait for their moment. And it always ends up coming. The adaptation of the youngsters is easier with the veterans explaining to them what everything is like here."
When asked if Mbappe was at the level of Ronaldo and Messi, Casemiro added: "I'll tell you one thing. Mbappe is an unstoppable player. My first encounter with him was in the Champions League in Paris, at the Parc des Princes. He did everything to us. We lost 1-0 with a goal from him, but it was crazy. He's the kind of player who will go down in football history. We can't ask him to always score a 9. But he never goes below 7.5 or 8. He's spoiled us.
Mbappé can make history at Madrid. Of course. On top of that, the lad has a humility that must be appreciated. He is playing in a position that is not his. He is doing well because he is very good. But, well, on the left is Vini. It is not easy to remove him from there (he smiles). This is football. It is not his position and without being a number 9 he is doing well. Credit to Ancelotti, who has convinced him to perform there. He knows that Kylian can also be a great centre forward."
