I can't agree that Barcelona doesn't care about winning the Europa League title. Because Xavi's career as a coach has just begun. However, Xavi's main goal now is to stabilize and strengthen the Barcelona team. And for this, he spent a lot of money to recruit star players. But at the same time, he will also wants to win the title. The Europa League title may not matter much to the Barcelona club. But it is important for Xavi's coaching career. And so I think Xavi will now prepare his squad to win both the La Liga and Europa League titles.
Of course, I think that's an assumption that actually doesn't make sense.
Meanwhile Barcelona is also fighting for another title where they have just qualified for the semi-finals of the Copa Del Rey after winning the match against Real Sociedad. So Barcelona really shouldn't ignore any opportunities as long as they still have the possibility of winning the title, let alone the Europa League title.
The Europa League title means more to Barcelona and Xavi after they failed to qualify for the Champions League. So I never thought that Xavi and Barcelona would ignore and underestimate him even if the Europa League is not bigger than the Champions League. Xavi seems very enthusiastic about the possibility of the Europa League in his cupboard this season, so I think he will be 100% there this season.
