I didn't mean to say that he is the best in the world, but when you try to give the whole situation an objective view, isn't Mbappe the one who creates the most enthusiasm in all the kids and younger players who look up to him? That is a value that goes beyond his quality as a player over a longer period of time, but the moments he has are definitely among the best the sport has ever seen.
We definitely agree that Mbappe is the best striker in Liague 1 at the moment, and it's natural because there Mbappe is supported by a capable squad and the League is not as competitive and hard as the EPL. I think if Mbappe moves to Madrid or let's say to an EPL club then he will feel the pressure and burden he bears in every game, I'm sure he won't get any better if he manages to move. Especially Mbappe has a high selfish attitude and this backfired for him to build good relationships between fellow players if one day he moved from PSG.
There are lots of examples of players like Mbappe and after joining another club his performance and quality slowly declined, because he didn't have a humble attitude and felt like he was a big star.
The demands, pressure and burden will be on his shoulders for the trust placed by the club and his status as a quality striker, Mbappe must maintain his performance in every match to bring his team to keep winning. A club as big as Real Madrid will have more demands, when the player is unable to maintain his performance he will always be blamed if his team loses. Bale had felt how hard it was to play at Real Madrid, despite his status before moving to Real Madrid as Tottenham's best player at that time.
Mbappe egoistic attitude is the strongest factor. He will experience a decline in performance he considers himself an important player at the club that other players must respect, this condition is certainly not good for the team and also for Mbappe himself. Humble attitude needs to be prioritized, he cannot play alone without the support of other players, when other players boycott Mbappe by not giving him assists, he will have difficulty scoring goals and improving his performance.
