There is no doubt that Xavi has done well for FCB so far, but I think there are several transfers that are questionable at the moment. As an example, it would always be better to get a first-team player rather than buying three or four average players. In comparison to buying three players, this will be a more efficient solution.
Just take a look at the attacking options they have available to them. Dembele, Lewa, Raphinha, Traore, Depay, as well as many more, are among the players they have. In fact, they don't even play them in the same position all the time. And I haven't even begun to talk about their defense yet.
Traore? Adama Traore has left Barcelona and returned to Wolves at this time.
But indeed to find players I quite agree with you that it is better to maximize the opportunities that exist because it is true that their young players like Ferran and Ansu are also very unfortunate that they have to stay on the bench and always change during rotation.
Instead of spending money again and again in the midst of a financial crisis, they are now better off maximizing what is available.
