And what will we see from PSG in the coming year? Mbappe has said that his next step would be to play for Real Madrid? I think Mbappe may never do that again at all. Only the only big problem Mbappe has is that he will not face any opposition in the cometition in France. So he can really only enjoy his level when he plays in the CL. Then you really should go to Italy or England. Spain is qualitatively a size below it. But I don't see an Mbappe in England happening anytime soon. Haaland and Mbappe together in the striker at Manchester City would not be bad. 
What's the nonsense about Spain? In what ways is Spain lower than Italy? I think that even if Inter, Juventus and Milan get the money together, they won't be able to afford Mbappe, but Real Madrid can. Another question is that Mbappe is too expensive as a commodity, he is like Neymar - very good, but the price is still higher than the sum of the positive qualities.
