I hope Barcelona is not expecting the new coach to take the team to win a trophy this season because that is what Barcelona and the fans used to do, bringing a new coach doesn’t mean that a team most win a trophy, although it will be good if a team win a trophy they should not be expecting it and when the team didn’t win anything and they will all started blaming the new coach that he is not good, the reason why I’m saying this is because I know Barcelona and the fans are not going to be happy if the team end up without no winning any trophy at the end of the season.
Barcelona president, Joan Laporta have a whole lot to accomplish. While Hansi Flick is new and we don't expect him to start winning games and lifting titles for the club. It will take lengthy time before things fall in good place for Barcelona. The club's board and the supporters always expect high from the team's headcoach, probably not good for the status for the club. Barcelona are suffering from injuries, budget inequity and also having crucial debts on their heads. The club's gradually draining because it's been one of the hectic challenges for them.
In my opinion, this actually all depends on Barca's management who should slowly improve their finances.
But it seems that has not been done and only thinks about how to improve the club's performance in various ways such as having debts with other clubs that cause new problems.
Barca's management should not need to do all that, just prioritize existing players or existing coaches and bring in free players from the transfer market or build young talents from the academy to be sold so that finances improve.
As long as Barca has not been able to show financial improvements in the future, Barca will only continue to get the same results because there are other clubs that have better finances to bring in better quality players.
