Hansi Flick proved himself last season, so there's no doubt about his performance this season. However, I think the numerous injuries will have a slight impact on the team's performance, even though there are adequate substitutes. I think things will be a little different.
This season, Barcelona is riding high on confidence after winning the title. What happened at the start of the season can't be used as a benchmark. I'm still quite optimistic that Hansi Flick will be able to bring Barcelona success again this season, possibly even better than last.
Last season was supposed to be the best season for Hansi Flick as the Barcelona coach because the team was on fire they were supposed to win the champions League of not the sudden defeat they got from Inter Milan would later couldn't stand PSG in the finals. Looking at the way things are going this season Hansi Flick will have some challenges in the team like injury and some of the players going out of form but he has already proven himself to be a good coach in his first season so the team still believes in him to deliver a better performance for them this season.
