In fact, PSG offered Mbappe a very large amount of money to stay at PSG, but all of that is the decision of the player, I'm sure Mbappe will leave PSG because if he stays at PSG then his career will never develop, now Mbappe is in a period of his glory and if he makes the wrong decisions then his football career will never develop.
I also hope that Mbappe will be willing to move to Real Madrid, it will be very good for his career.
And the Real Madrid team are in dire need of a striker to replace the departed Karim Benzema and I think Mbappe is a perfect replacement.
You are right but if Mbappe leaves PSG there will be some problems of losing an attacking player.
But on the other hand, Mbappe does need a team that can make his career increase, plus a big team like Real Madrid really want him.
It will be a new era for Real Madrid if they can bring Mbappe to play there.
Even right now, situation is not clear about Mbappé but as things are going most chances he will join Real Madrid, and surely they could be again at their best because he is impact player and can change results by himself but as Real Madrid having many quality players things can go impressive for them in coming years but right now first thing is can PSG selling him in this year because after his refusal to extend contract suddenly things take another change and PSG management is also not happy with the leaked video where Mbappé is sorry for his last instant against Real Madrid.
Right now main issue is, can Real Madrid buy him on current price, or he will leave for any other club because PSG will not cut his price if he's not going to extend his contract and Real Madrid president already saying they will not buy him on this price is another interesting twist.
