Yes, if I'm not mistaken, he's been a good player for Monaco, before at PSG. After PSG he developed amazingly. But we see at the moment he is still in one league, meaning there is not too much adaptation to the style of play. While there is no evidence yet for Mbappe if he goes out of the league. For example next season he goes to Madrid, I don't feel he can adapt immediately. But it is a great hope that they will always be able to play well with a new club.
