Barcelona was able to finish this season as runners-up after stumbling in the first half. However, Barcelona failed in other competitions such as being knocked out of the Champions League, the Blaugrana then also failed after being thrown into the Europa League. Their steps in the Copa del Rey also only reached the round of 16. Xavi of course realizes that this season has been a bad season for Barcelona, but the presence of Xavi has been able to save the face of the blaugrana from worse. Looking at Barcelona next season will definitely improve, Xavi will recruit several players to strengthen the squad and be able to compete for the title.
Apart from wanting to bring in some new players to strengthen his team next season then I think Xavi also really wants to keep some of his potential young players. Dembele continues to develop and he has become a player that is expected to be kept in the next few seasons, but the player has not yet decided whether he stays or chooses to move to another team next season.
Another important position is defender because Alba and Alves are also not always able to help the team throughout the competition. They are injury prone and I think they need to get a decent cover next season.
