I don't know about Zidane coming to manage PSG but I am quite sure that Kylian Mbappé is going to move to Real Madrid next season.
Even though I have been a Barcelona fan for quite a long time, I can't deny this, Real Madrid knows how to conduct with players far better than Barcelona. I also think that his playstyle is going to really match with the squad of Real Madrid.
Kylian Mbappe is indeed one of the players that Real Madrid is targeting, and it looks like Mbappe wants that too, playing for Real Madrid.
Yes, Mbappe's playing style will suit Real Madrid, he will be able to fill Real Madrid's void in attack, such as when Benzema can't play, and affect Real Madrid's attacking performance. I believe Mbappe can do that.
