Real Madrid seems to be the most obvious club for him, but I would have also liked if Manchester City tried to sign him and he could become a left wing attacker there. Together with Haaland they would be a crazy offensive duo, but I guess that is not going to happen. Although I wonder whether there have ever been any approaches by Manchester Cit to check out whether they would have a chance or whether they don't even need to try. They would be able to do it in terms of the finances, but it would almost be too good to be true if that were to happen.
First of all, Real Madrid president, Florentino Perez is a big time admirer and a big fan of Kylian Mbappe. Real Madrid is a premier club in La Liga, and they are very strong competitors in every competition. They are the only team that has considerable advantage to bring in the Frenchman. The Los Blancos have been trying to sign him since day one, and nothing has changed at the time lately. After Messi and Ronaldo, Kylian Mbappe is one of the few good players in football. Manchester City have shown little interest in bringing him here, despite the fact that he is a talented player who can play for any club, Pep Guardiola already have the sets of players to work for next season.
