With a difficult financial situation, I think Flick will have a hard time. A few weeks ago I read that Flick could not be officially registered as a coach Barcelona in La Liga. If this continues they don't have a good chance of player transfers, unless they get a new flow of funds. Due to the main contender, Real Madrid is currently in great team form due to quite good player transfers. Because of this, I think Barcelona will get heavy pressure from other teams who will still improve with the transfer market.
Barcelona will compete with Real Madrid next season, we hoped both team are able to sealed in the top position next season. Hansi Flick is the new headcoach for Barcelona but there's more to his managerial position. Barcelona and their supporters expects high of Hansi Flick because looking at his stats and accomplishments for Bayern Munich, he made good records and always winning, they hoped the same thing will happen in Camp Nou. Perhaps they should also consider the part where the club's is facing challenges and restrict orders when it comes to signing.
When Laporta considers what Hansi Flick achieved at Bayern Munich, perhaps he should also consider that the two leagues have different competitive characteristics and the most impressive thing about Flick at Bayern Munich was when the club managed to win the Champions League.
However, the decision has been made and Barcelona will start a new step with a new coach, but in terms of player material, Real Madrid is clearly above Barca so there is not much hope that Barca will be able to compete with Real Madrid for the LaLiga title, maybe Barcelona will be strong in other local competitions, while for the Champions League it really depends in the draw, a heavy group will only open up the opportunity for Barcelona to be eliminated early.
