You can compare Real Madrid with Barcelona considering the situation of these two teams. Real Madrid is loaded with money with Barcelona just hiring Flick as a coach who couldn't have good performance recently and I'm sure they can't even give him and enough tools to have good performance in the team.
Yeah, I agree with you. Barcelona need money now. Barcelona cannot strengthen their squad without big funds. Barcelona need experienced and talented players in their squad. Xavi was a good enough coach. Xavi helped the team win the La Liga title the previous season. But Barcelona needed to strengthen their squad this season. Xavi could not strengthen the team due to lack of money.
Barcelona's new coach Flick is experienced, but without a strong squad, he will not be able to stabilize the performance of this team. I have no doubts about Flick's capabilities. But along with experienced coaches, a strong squad is also needed.
Barcelona's salary fund has swelled too much. It is unclear how President Joan Laporta will solve this problem. They will likely have to sell off stars who are not in the new head coach's plan to reduce the salary budget. In addition, President Laporta implemented a series of "financial levers" as well as reducing the salaries of many key players, even "forcing" midfielder Pique to retire early. I think the person who needs to be replaced just now is probably President Laporta.
I guess coach Hansi Flick will not stay in Spain for too long, because from the beginning, he was just a gamble to save President Joan Laporta's bad tenure. Both Coach Flick and a long-term sports project are just illusory fantasies drawn from the weak capacity of Laporta. A shakeup is about to happen. After Xavi's unjust breakup and in the context of Barcelona's many delicate issues, Flick was embarking on an adventure in which he had little hope of success.
