Actually, Xavi's work was good in his first season coaching Barcelona, winning the League and last season finishing in second place, of course it's not bad but management's satisfaction is not to continue. Opponent squad next season: Real Madrid and Girona were Barcelona's tough competitors in the last two seasons, but I don't believe Hansi Flick will be able to make Barcelona a strong competitor or vice versa, because his work has not been seen by everyone. Bringing Barcelona's name is not easy. like turning the palm of the hand, hopefully Hansi Flick can prove it next season.
regarding Xavi dismissal, it wasn't because Barcelona management was satisfied or not, but there was something being hidden from the public regarding the pros and cons of Xavi, who was initially going to leave but management retained him, but after Xavi decided to stay, he had to be fired without any reason and chose Hansi Flick as a replacement.
of course he is recognized as successful in bringing Barcelona to stay in the top 3 of the standings without quality players and that is one of the pure successes of Xavi intelligence and experience so far who has been with Barcelona able to explore the team's shortcomings and correct them very well so that Barcelona is able to get good consistency.
there is no need to doubt that last season Barcelona under Xavi still failed to compete with Madrid, while in the following season Madrid will have a pure striker who will become a scoring machine that is difficult to stop and the bad news is that we have to see Barcelona with the new coach competing with Madrid who very hard to beat.
what I said does not mean that I doubt Hansi Flick, but overall the new coach's experience is not that great and the heavy pressure that Hansi Flick will face when he has to rotate existing players without being able to bring in the players he wants, but at least we give Hansi Flick the opportunity to prove whether he deserves to be recognized as a great coach like Xavi.
