I guess Xavi is the happiest person in La Liga because he got what he wanted to get with his team where they know him as a legend and he is coaching Barcelona for the first time his coach in Europa and top teams, Barcelona is in a financial situation in which they can't spend money like Real Madrid and this definitely could affect the results of Barcelona but in the end, Barcelona won the title.
But in the next season, I think Real Madrid can buy better players to have a closer race with Barcelona for the title.
Barcelona is indeed great even though it is in various problems such as financial problems and being accused of a bribery scandal to the referee, but Barcelona can win the Spanish league this season. I also think that with Barcelona's achievements this season, Xavi deserves to be happy.
But Xavi's real job is next season
If last season we managed to finish runner-up and this season we won Laliga, then next season it is clear that the target is the UCL. Can Xavi go to class?
If you look in the mirror for next season, the toughest competitor is, of course, Real Madrid. Especially now that Real Madrid has started to build a stronger squad. If this season Real Madrid only brought in Rudiger and Tchouameni, then next season they will already have Bellingham, Wonderkid Endrick Felipe and are certain to bring in a mature striker to replace Benzema. The question is whether Xavi is ready to fight next season?
