Strangely, when Mbappe sent a letter to PSG stating that he did not want to extend his contract, it was leaked to the media first and this seems to indicate a bit of a plan between the two parties. Apart from that, it has been confirmed that Mbappe will indeed leave Paris and it seems that PSG also don't want to lose, therefore they want to sell Mbappe immediately in the summer and don't want several clubs to wait for his status until he is free agent in 2024.

One of the clubs that have been interested in Mbappe for the past few seasons, namely Real Madrid, seems to have started to move after hearing this news and they don't want to lose their chance in sight. I think another reason Real Madrid have delayed a bit longer in signing Harry Kane is that they are waiting for something like this to happen and I think if Real Madrid can sign Mbappe that's even better than signing Kane.
