The major issues for flick would be the fact that Barcelona themselves are almost entirely broke and for a club like Barcelona that wants to return to their former glory they would definitely need to bring in some players and that would require funds which at the moment seems to be some of their issues but even at that I still expect them to be different atleast they have some good players, it just all boils down to the fact that a good coach with good mentality needs to handle the club.
Hansi Flick will be successful in his new club although he will encounter top challenges which will probably make things really rough and tough for the new coach. Barcelona are facing financial crisis and we totally understands how everything can play out because there's more options to explore but due to their inability to tabled in for sufficient resources, they might as well quit from solid budgets, more similarly in buying top talents. Hansi Flick will do his best to apprehend the performance of the club and we totally understands the point of the club.
