Of course they are coming back from the collapse of last season and returning the league champions is a natural thing for now. So they tried to return to being king of Spain after being destroyed in the previous season. Adi is natural. But I thought before, with the state of player spending Barcelona have done, they would be able to talk a lot in Europe, but I was wrong. After I think about it, maybe it's not the time yet. So it looks like they need a longer process to advance to Europe. Xavi is unlikely to perform in a year this season, maybe next season. They haven't quite had the mentality after their experienced players left and retired.
Rebuilding is a process. It's not going to happen in one year. Last year when Xavi took over they finish the season without a trophy. This season they finished the season with two trophies. We can clearly see the improvement in the team and also in the management. The previous management did ridiculous deals and signed many unnecessary expensive player, but this management is different. Things are even more difficult for this new management because they have to sign top quality players for very low amounts because the club in a financial ruin, a ruin caused by the dealings of the previous management.
If Barcelona get the players they want in this summer transfer window they will most likely compete in Europe except they suffer injuries again as they did this season.
