I think Barcelona already has potential star players in it, but it has to be in the right hands, now the financial crisis hit by Barcelona is an obstacle to bringing in star players who have a lot of experience.
Hansi Flick's hard work for Barcelona will produce real results in the future as Ansu Fati, Yamal and Torres are talented players and they also play on a suitable team. Hansi Flick's hands can make them future football stars.
This season, Hansi Flick still has to work harder to make the players you mentioned into stars in Barcelona and also in the La Liga scene, because Hansi Flick himself is still very aware that the level of competition in La Liga is still quite high and must be able to be fought with better performance. The big win that Barcelona got yesterday was only because their opponents were not balanced enough against their strength so that Barcelona was able to win with that score even though the game played by Barcelona was also very good in the match.
