I don’t think that Flick will be given such a serious task; even Xavi, after the championship season, was given the task of taking any two titles, that is, the season would be successful if Xavi could take the cup and the Spanish Super Cup. Most likely, Flick will also be given a similar task; demanding the La Liga championship from him is not adequate.
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.
