I hope Barcelona solves the existing financial problems to strengthen the squad more. Otherwise it is hard to compete with Real Madrid.
This is not easy, because currently Barcelona no longer has mega star players like Messi, Neymar and others. The only way for Barcelona to have good finances and solved all of their financial problem is to sell the club to a rich businessman, for example from Saudi Arabia. With this way, all of Barcelona debts can be paid off. However, if it only relies on sponsors, broadcasts, jerseys/merchandise, tickets, I don't think it will be enough to solve their financial problems in the near future.
I agree, even if Barcelona manage to get a treble winner, the reality is that Barcelona will still have financial problems because the debt Barcelona has is very large. So yes,I agree with the option of selling the club itself, because ifBarcelona continue to do the efforts they have done so far, then ofcourse Barcelona will not only be difficult to win trophies, butBarcelona will also be difficult to have mega star players in the squad. Therefore,at least Barcelona might still be lucky to be in La Liga,because if Barcelona were in Serie A then Barcelona would most likely already have been punished.
