What does Xavi have to do with bringing Barcelona back to glory with the Europa League?
I don't think Barcelona and Xavi need to be discussed here anymore, because the winner of the Europa League is already known. Barcelona's failure in the Europa League is an old story, after all, next season Xavi will lead Barcelona in the Champions League, not in the Europa League.
Well, although he said it in a somewhat harsh way, you are right, Barcelona had a very big failure in the Europa League, I would not think of Barcelona at the moment for it, rather it could make a difference with the Spanish league. that both Xavi and Barcelona managed to do something significant like being in the first places, I wouldn't say that they were in the first place or that they were champions, but if they could stay in the top 3, maybe that way they would once again be one of the best teams from Spain, Europe and the world, they have respect in football, the only thing left is for them to show it on the pitch.
Barcelona should not think about their failure too much right now because they started the season really badly and they ended up finishing in the top two, which is an achievement in itself in my opinion.
Barcelona is going to concentrate on doing well in La Liga next season. They will also be trying to do well in the Champions League but I don't know if they will be able to achieve any great thing in the Champions League with the current squad. I think they should concentrate on La Liga right now and over time they will make their squad stronger through some transfers and they will be able to concentrate on the Champions League then.
