Barcelona have continued to work on many solutions to maintain the financial stability of their current club, various ways they have done including selling star players, cutting wages, selling young players and even reportedly when Barcelona also no longer give lunch to young players who train in their academy just to prevent the club's expenses from growing, And reportedly this season Xavi coached Barcelona for free because indeed he has given this season's salary to barcelona so that the club's financial stability is maintained.
I don't know where you got this news because I'm sure there are many rumors that are very different from reality. Barcelona are of course in very poor financial shape so far, but they have really had a great season with all the effort they have put into it. The players have made sacrifices by cutting salaries, Xavi has to accept the fact that he doesn't get a large spending budget, while there are still many other things being done to keep the club afloat.
I'm not sure other clubs will be as good as Barcelona if their financial condition is as bad as Barcelona's. Xavi and the squad and management have done their best so far and basically they are quite successful and competitive. The problem is, some fans and other people don't appreciate this because high demands are one of the most burdensome things for anyone currently at Barcelona.
What Barcelona are doing now is indeed very capable to make them continue to stay in La Liga and also continue to exist in champion league, but I think precisely what Barcelona are doing now in defending their team is like a time bomb that can explode at any time, and of course over time Barcelona's burden will greatly increase in the future if they cannot get an effective solution to overcome the problem Their finances so far, or indeed maybe Barcelona should have been taken over by another party who is indeed able to provide a large investment to solve all of Barcelona's current problems as you said, so that way we will be able to see Barcelona again can dominate the Champions League like the previous season., Btw if Barcelona can win the Champions League this season will the prize money obtained be very large and can make Barcelona's finances stable again?
They improved it last season and made quite good profits at the end of the season. Of course it didn't solve anything, but they did their best. What Barcelona can be most proud of is that they were still able to give their best when their financial conditions were very bad.
