Kylian Mbappe is having another awesome season right now. He has played in 27 official games so far. And he scored 19 goals and made 17 assists in these games. His market value seems to be €160m. But as we all know, he is available for a free transfer as he hasn't extended his contract with PSG. The team are trying their best to convince him to stay here for at least one more year. But he doesn't seem to have such intention. He wants to go to Real Madrid and he will in this summer.
I doubt that they could actually convince him to stay, if he wanted to stay then he would have accepted an offer already. To be fair, when you are a player like Mbappe, team should just sign an empty check and send it to you, because at that level you decide how much you are getting paid. If I am not entirely wrong, at one point Messi got like 70 million right? Which is not all because he is the greatest player in the world but also his jersey was sold all over the world, whichever team he wanted to go, would have 200+ million jersey sale, no idea how much PSG got from it neither, maybe a lot.
So, it is a bit more about popularity and Mbappe has that too, so he could just tell them what he wants, and they will definitely pay him, hell 100 million doesn't sound like an impossible amount if you ask me. This shows that Mbappe is not staying, if he wanted to, he would just give them an amount.
