It would be quite difficult for both people to work together if they had a disharmonious relationship, and that's what happened between Xavi and Laporta. One of the things that made Xavi want to leave Barcelona before was because he felt that he did not get full backup from Laporta (including financial support) but for a certain reason Xavi decided to do a U-Turn.
That seems like good news for Barcelona fans because Xavi is still willing to carry out his role but, it turns out there was something that made Laporta furious with Xavi. It seems like Xavi's words are that he feels that Barcelona will not be successful if the same method is used next season, which was the trigger.
Everything has happened, Xabi will not manage Barcelona next season, Barcelona management has appointed Hansi Flick as his replacement. Barcelona new era will begin with a new coach next season, perhaps there will be some surprising transfers made by Barcelona to facilitate the new coach. Barcelona failure to win a trophy was not because they were incompetent in managing the club, the financial problems they were facing meant that Xabi had to work hard to maintain Barcelona performance despite all the limitations in his squad. Xavi has succeeded in promoting several young players from La Masia as future stars for Barcelona. If Xavi is entrusted with managing Barcelona for the next two years, Barcelona will reach its best level again with players who have tiki-taka DNA.
