I agree with you. We heard news that Xavi will not stay with Barcelona next season. But in the end we saw that Barcelona sacked Xavi. I don't understand why the Barcelona management took such a decision. Xavi was quite successful with Barcelona. Barcelona's squad is not strong enough, yet the team occupies the second place in the table.
Hansi Flick became the new coach of Barcelona. I don't think Hansi Flick is very experienced. However, he was quite successful with Bayern Munich. But Bayern Munich's squad was also very strong. But Barcelona's squad is not strong enough. At the same time, financially, Barcelona is now in crisis. So it is unlikely that Barcelona will dominate La Liga next season with the help of Hansi Flick.
Laporta really praised Xavi previous performance and he really hoped that Xavi could stay with Barcelona, but this was just empty talk because after Xavi expressed his desire to stay with Barcelona, the management instead fired Xavi. I think the big failure of Barcelona management is of course that they don't have patience so they would rather look for a new coach in order to bring them lots of trophies every season. Xavi performance is not too bad this season because he managed to bring Barcelona to the quarter-finals of the Champions League and also closed the season in second place in the standings.
However, this does not make management satisfied with Xavi performance this season, so they prefer Hansi Flick as Xavi successor next season. Regarding experience, of course Hansi Flick certainly has a lot of experience, but that was in the Bundesliga when he coached Bayern Munich. So Hansi Flick performance in the first season with Barcelona will of course steal a lot of attention where he will be required to bring better changes to Barcelona. The target of winning a trophy is a tough target and of course it will be quite difficult if there are no major changes that occur in their squad, meaning they have to have a lot of quality players to be able to compete strongly with Real Madrid.
