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.
Yes, to be honest, Barcelona this season is not too bad considering the many obstacles that occur in the club, we should appreciate Barcelona in this season position 2 is not bad, but I'm not sure if next season Barcelona will be able to compete considering the different games of Xavi and Flick. And with the club's unstable finances. Making flick will not be free to buy the players he wants for his tactics later,
Yes I hope Barcelona will be able to compete next season with different tactics.
If we talk about tactics, of course it will be different and the difference will probably seem quite large. I think Hansi Flick is much more reliable than Xavi and everything will change as long as no problems come. Maybe Barcelona should be able to strengthen their players' physical strength so that they don't get injured as often.
I am very sure that if most of Barcelona's players can avoid injury then they will be much calmer in navigating the competition next season and at least they should not be outside the top four in Hansi Flick's debut as coach. However, if we talk about competing with Real Madrid, it will still be quite far away and it will be difficult for Barcelona to match it.
