I agree with what you said about the solution to improve Barcelona at this time by switching to new ownership then maybe we will be able to see Barcelona rise again, but unfortunately the club owner and management are reluctant to sell Barcelona and prefer to solve their problems by reducing the salaries of players, management and even selling their star players to other clubs to at least cover their financial problems,With this decision from management remaining adamant, of course Barcelona is even more shackled and will only continue to decline for the next few seasons.
I wonder how long Barcelona can survive in a situation like that. Management's decision not to sell Barcelona will cause the team to suffer further losses in the future. I think Barcelona really needs a new owner with sufficient funds to rebuild their squad. Xavi is a good coach but some players can't play with the tactics he uses. I don't blame the players but with Barcelona's current financial condition I think Xavi still doesn't have the opportunity to prove himself as a coach because the team doesn't have the money to recruit the players Xavi is targeting.
You have made an absolutely correct and appropriate observation. I think Xavi is a good coach, but he can only make the most contribution to the team within the framework of the opportunities offered to him. As we can see, they are in third place this year and there is only a 2-point difference between them and the second place. Actually, there is no bad ranking, but when the team is Barcelona, the expectation is that they will be in the championship race. They can only meet this expectation if the desired players come.
