It seems that the transfer of Mbappe should in theory already be completed, if we are to believe all the rumors of recent times. A nice detail is that Mbappe will play football with his current employer PSG against his potential new employer Real Madrid. That will be a match for Mbappe where he can prove himself enormously towards PSG, but Madrid would rather not have seen him play now. I sometimes wonder to what extent a football player has a certain amount of guilt if he knows that he will almost certainly move to the other team in the new season.
I mean it is technically not done, but where there is fire, there is smoke. Most of the time all these talks end up being done if they are certain in the talks. Dude wanted to be in Madrid for as long as I can remember and he will surely leave to be there as well. How will Madrid approach this and how well they will do is the question mark.
There are teams with better roster than them in many leagues and they are getting older, they need to refresh the team with some young players and I do not know if they will be able to do it properly. Doesn't mean that they can't, but it just means that they will have some hard time doing it for sure. I hope that they could get a few more players from great teams to bring the team overall higher, instead of just one player.
