Xavi leaves a lot of convenience for Hansi Flick in continuing and improving Barcelona performance next season, hansi Flick of course now has a team that is actually strong enough to compete next season, so Hansi Flick only needs to adapt his strategy and style of play to the Barcelona squad this time in my opinion, next season, I personally hope that Hansi Flick will try to focus more on the domestic league than the Champions League next season because in my opinion their squad is not capable.
The performance of Hansi Flick's coaching will be clear after the season has been running for some time or before the break starts again next season. Because now everything can be assessed and predicted, but this will also not be precise enough because remembering that there is still the possibility of change and the opposite happening to a team. I also see that it will not be easy for Hansi Flick to undergo his coaching period at Barcelona because Barcelona's target is to be able to beat Real Madrid in La Liga and also in the Champions League next season.
Xavi may have left a solid legacy at Barcelona but even without all that, I think Hansi Flick will be able to achieve success with Barcelona as long as he has full support from the boss. Hansi Flick is a good coach, and I think Barcelona was very fortunate to be able to sign him to replace Xavi. The only problem that might be the biggest obstacle for Hansi Flick is Barcelona's financial condition which might prevent him from being free to recruit the players he wants.
