Joan laporta warned real madrid when they were chasing after Mbappe but they refused to listen. When there are too many star players at a club, it destroys the club and not make them better as they'll all have pride to work together well and bring success to the club. This isn't the first time that Real Madrid has tried to bring many talents together but it always failed until few of the talents leaves the club. I think Mbappe is a good player and if they want things to change, he should be played in his right position and not being played as a striker. He isn't a striker and has not played that role before therefore everything is new to him and he isn't performing well.
Mbappe must remember that he has to be a "number 9" and forget about the left wing. He has played very well on the left wing and now he has to play well in another position. There's a lot of pressure at Real Madrid, this is not PSG. One piece of advice? He shouldn't give up.
Mbappe's talent is undeniable. He still has a long way to go to truly become a key factor at Real Madrid, especially when the Champions League is always the most accurate measure of any player's ability.
