Let's be realistic. Whoever replaced Xavi this season could not have won this cup. Xavi managed Barcelona in the best way possible and handed the team over to Flick in second place. We will watch together what Flick will do next year, but there are no big differences between Flick and Xavi. If Xavi wanted to go, of course his decision should be respected, but if Barcelona wanted to send him, I think they are making a big mistake.
If we look at Barcelona's performance since the start of last season, we can see that Xavi is actually a good coach, he has a good leadership spirit, it's just that the competition with Madrid is very tight, Madrid has more of a winning mentality than Barcelona, regarding whether Flick will be able to bringing Barcelona to be the last in La Liga, I also doubt it, just being able to finish in the top 2 would be a good achievement for Flick.
