The Laliga championship is the one Barcelona shouldn't lose, at the very least. The champions league, however, is not one of them. Barcelona is still in the process of developing, so they can't aim to win the UEFA Champions League by next year. The Barcelona players, as much as the fans, are aware that they haven't developed to that point yet. Building Barcelona back up to the powerful team it was during the period of Messi, Xavi, and Iniesta is going to take a lot of time.
I'm interested to see how Xavi plans to add new players to the Barcelona squad despite the club's ongoing financial difficulties.
To be honest, if you will not even find messi, xavi and iniesta again. That era already passed and we are heading toward the new era where so many young talented players become next generations of great players.
Barcleona has some great young talented players like gavi. The fact that if iniesta is still looking for the professional player that can help the young talented player to be even better.
That's why arsenal aimed to get some fully experinced player like gundogan or someone else.
Im fully aware if the next target aimed by barcelona will be UCL but there must be so many improvements to be made by barcelona to make it happen.
