At the moment I don't see any young PSG academy players having a candidate capable of replacing Mbappe for now. One of the best ways is to take advantage of the transfer market by buying new players. Some media outlets suggest that Victor Osimhen, Rafael Leao, Bernardo Silva are reportedly new targets to replace Mbappe if he leaves. After he officially leaves, Enrique must be able to make a collective game, not rely on 1 player.
