That's right, Xavi became an important part of the rise of Barcelona. after the difficulties at the start of the season, Xavi gave a new spirit to the game of Barcelona. that's what led Barcelona to rank 2 at this time.
maybe this season Barcelona is still without a title because it was not Xavi's target after he arrived at Barcelona. but for next season, Barcelona will bring in new players to support Xavi for a trophy.
Looking at the current barca squad I don't think they are ready for the title next season. But the arrival of Xavi in the middle of this season was able to bring a good atmosphere in the team. But I think Barcelona is in time to build or rebuild a squad that can bring back their glory like in previous years.
I think the Barcelona squad under Xavi's care is now ready for next season's LaLiga competition, strengthened by the arrival of a few more. I am sure that next season's La Liga title will definitely be obtained by Barcelona, and what is a breath of fresh air for Barcelona is Ansu Fati's return to the Barcelona squad after suffering a long injury.
Ansu Fati is a talented player. I wish he can proceed with his exhibition. Without injury Ansu Fati is far superior than others, he should take care on it otherwise he'll turn into waste as many players survived. Along with Ansu Fati, many talented players are there in the squad but because of their financial crisis unfit to compete any summer transfer. End of the season many players also leave the club, which is my concern how could they manage the change and can give good fight next season.
