I totally agree that Barcelona need big improvements fast and hiring Hansi Flick as new coach is good move. Club president made smart choice in picking Flick who has reputation for getting great results. With Flick in charge Barcelona can expect fresh start and clear direction. However club struggles to sign top players have been big problem and it is disappointing to see them miss out on chances. Xavi Hernandez had potential as coach but he did not quite meet expectations. I think Flick leadership will bring necessary changes to help Barcelona succeed and achieve their goals.
Everything will depend on the support of Barcelona management because if they are not able to improve by bringing in several new players then I don't think Hansi Flick will make Barcelona rise.
Xavi is actually also a coach who has good qualities, it was proven when he first arrived that he made quite a lot of positive changes, but the Barcelona management did not provide strong financial support because the Barcelona team was having problems, the same goes for Hansi Flick next season, I think Hansi Flick should be in provide financial support to bring in some new players otherwise I doubt that Hansi Flick will make the team even better.
