Barcelona's back line was quite fragile last season, they didn't have players capable of breaking attacks from opposing clubs, so they conceded more than 35 goals, but it seems that wasn't Barcelona's only weakness last season, since Messi's departure. Barcelona seems to have lost their best game, even though the composition of the players was not that far before Messi's departure, Messi's dependence on Barcelona was quite visible after his departure, Xavi had a tough task, rebuilding this club to get back on track
And now it has begun to be seen that Xavi is indeed able to build the Barcelona club to be on a better path after having slumped last season. Messi's departure does not have a good impact on Barcelona, but Xavi also does not want to see the Barcelona club drag on for too long in such conditions. So he has done everything possible to rebuild the spirit of the Barcelona club to its best form at the moment, and I am sure Barcelona will be able to compete again in La Liga next season.
Not that easy to build a club, one season is a short time to fix all the shortcomings that exist, but in contrast to Barcelona, they are not so worse in the past season, so it is likely that Xavi is easier to overhaul the team.
The problem is at this time, the new players they buy cannot be registered, because the club's finances are not good, so it is constrained by the list of new players, there are only a few options, selling de jong or other players who have a large salary in Barcelona
