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.
Mbappè is a player from the AS Monaco academy and he has developed into a good player since joining the Monaco league 1 club, even during his season with Monaco Mbappe presented a trophy for Monaco in league 1, making PSG interested in recruiting Mbappè from Monaco and finally PSG was able to have him in in 2017/18, it would actually be quite a shame for Monaco if he kept Mbappè for a long period of time, maybe Monaco could achieve success like PSG and Mbappè could be used as a long-term investment but Monaco only used him for 2 seasons, maybe Monaco didn't know that the player from the academy will become a talented player like now and become a target for the team that will have him.
