Barcelona will not let go of his star players now because they see from what has happened to some of their young players as much as any offer they still will maintain the player. We've seen Ansu, Gavi's offer and even De Jong but Barcelona remained firm with the establishment of not selling their young players.
Now for Lamine Yamal, he is a player who is indeed the backbone for the future of Barcelona.
Yet if in the end Lamine sold it would clearly change Barcelona's finances for the better, but it would not be done.

Barcelona always retains the players but it is a blunder for them because after all what they showed from the beginning they were always late to sell players who in the end made them losses because their star players left with a free agent status.
Actually this is a density but back again this is Barcelona who is always difficult to release players and for PSG now they only have to try harder to find good winger as a Mbappe ruler next season.
