I would also say that, but I think Barcelona has moved up a level compared to last season. Their defense is improving, the midfielders and strikers have been very good, so I think it's only a matter of time. If Barcelona is supported by good financial conditions, then I'm sure Xavi can build a stronger team. Xavi needs a good left wingger instead of rotating Dembele and Raphinha in those two positions, but if Ansu Fati and Ferran Torres do well then that will also help a lot.
Xavi still needs many of players to establish his performance in midfield and attack, but financial problems have so far prevented the realization of those plans. But after all Barcelona can still compete with the current composition of the team, but it is difficult to achieve great success in Europe.
Ansu Fati and Ferran Torres deserve to be let go, if there are better offers. or, at least, Torres would be better off let go. Raphinha, I haven't seen his best yet. in fact, its performance tends to go ups and downs. well, if Xavi wants to build a stronger team, he must first bring in a successor to replace Busquets. at the very least, one that was almost on par with him both in experience and ingenuity when it came to managing his teammates. there is no choice, if Xavi has to persuade Gundohan to be willing to play with Barcelona.
For defenders, I think Barcelona is quite strong but it seems like Kounde still needs a better adaptation because sometimes he underperforms several times.
for me, ideally Barcelona let Raphinha go. because it seems that he does not suit the style of the system that Xavi applies, Bernaldo Silva can play in various positions instead. well, for domestic competition. I'm pretty sure, if the probability that Barcelona has to defend its title is wide open. but in this competition, I doubt it enough if there aren't many changes that Xavi has made by bringing in several newcomers. unfortunately, they have financial problems.
