Real Madrid needs desperately a player like Mbappe in order to achieve their goals much faster,a player like him in the middle of the stars of Real Madrid will shine much brighter than he is doing in the Paris team.I think it is time for him to move as he played several seasons there with Paris and never managed to win a Champions League trophy,he is young in age yes but the years do pass and it would be better also for him to go and join a team like Real Madrid.
I would not wait for other offers if I were him,as soon as Madrid would have contacted me I would have immediately agree with their offer,Real Madrid is the best team for me where Mbappe can go and upgrade his career with a Champions League trophy.
The years are passing quickly, absolutely. But Mbappe knows that, he is aware that losing another season at PSG can cost him a lot in terms of his achievements as an individual player. I think it is already sad that he wasted a couple of years at PSG. It was entertaining in the beginning when it was Messi, Mbappe and Neymar, but retrospectively it didn't help him much except for becoming rich. But he would have become rich in any other club as well. Now he is in his mid 20s already and time is running. He could have broken dozens of records, but that is becoming more difficult now.
