Hansi Flick will have difficulty to improve Barcelona defense if he wants to gain success with Barcelona. If he fails to improve defense system for Barcelona, there is very small chance of success there. Furthermore, attacking power of Barcelona was affected a lot last season with decreasing performance of Lewandowski because of ageing. Ageing effect on Robert Lewandowski can become bigger in a new season and this bring another big difficulty to Hansi Flick.
Barcelona don't have the luxury of buying as many players as they want. Unlike Real Madrid, who can buy any player they want, Barca's financial problems mean they have a spending limit. Therefore, Barca need to build a very balanced squad. Therefore, for Hansi Flick to be successful, he will need to keep players like Vitor Roque, Eric Garcia and he will need to know how to get the most out of every player at the club. For now, Hansi Flick's job is not easy and Xavi said before leaving Barca that Flick must be ready to suffer.
That is the burden that every new Barcelona coach must carry. Limited funds mean they can't sign as many players as they like. If for example, they have to sacrifice old players to bring in new players, it might be a solution, but it doesn't guarantee that their performance will improve because the players who leave may have made a contribution to their previous performance. However, if in these conditions it turns out that the coach can give the trophy, then it will be an invaluable source of pride because, with all these limitations, the coach was able to show his greatness.
Barcelona currently has financial problems that allow them to be selective in bringing in star players, but to say they don't have the money at the moment seems we are very wrong, because however, currently Barcelona is very active in bringing in several new players in order to strengthen their squad next season,Besides that, isn't Barcelona currently the club that pays the highest player salaries in La Liga?
Currently Barcelona defense looks a bit weak when they won over Manchester City in yesterday's friendly match, but I think this is very natural because Hansi Flick fielded a young squad in their defense and maybe we won't see this in official matches next season, But even so, of course they still need additional players in their defense line for next season, currently Barcelona is reportedly only one step away from recruiting Dani Olmo after all personal terms have been agreed between Olmo and Barcelona, then why do we keep saying that Barcelona doesn't have the money to support of Hansi Flick?
