I don't think there's anything wrong if Barcelona or its fans hope that Hansi Flick can bring Barcelona to a trophy next season. Because if for example the fans or the Barcelona side don't hope that Hansi Flick can bring the trophy to Barcelona, then what should they do? The point is, don't think negatively before next season starts. Because we don't know for sure what Barcelona will be like in Hansi Flick's hands, it could be that Barcelona shines again or vice versa. Therefore, the fans and the entire team at Barcelona must support and encourage Hansi Flick totally. Because with the enthusiasm given, Hansi Flick will definitely be even more enthusiastic about becoming a coach at Barcelona. Apart from that, Hansi Flick also said that he would try to restore Barcelona's glory days. He also admitted that he was very confident that Barcelona could definitely win the trophy next season, as long as they put in a lot of hard work.
Actually not wrong with Barcelona's fans expectation after success signing Hansi Flick as manager and he can brings Barcelona become the La Liga and Champion League winner, but most of them must realistic regarding financial difficult and Barcelona until right now not sign any new top quality players although linked with many top player such as Dani Olmo and Iñaki Williams.
Barcelona have try many ways for signing Iñaki Williams but still not reach agreement deal how difficult for spending around 50 million euro as fees transfers.
No doubt with Hansi Flick tactician and his achievement when becoming Bayern Munich manager, but difference with Barcelona less financial support and he can't sign any top qualities player seems under 40% possibility for Barcelona winning the La Liga next season. I don't sure easily with any manager without support much money for winning domestic league tittle and make their team keep perform well.
