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.
Barcelona's increasingly worrying financial condition is the main problem at the club. In fact, according to Barcelona's former financial advisor, Marc Ciria, he said that Barcelona's debt is estimated at 3 billion euros. And that is a very large number. But maybe if in 2014-2015 this club had not mismanaged its finances then something like this would not have happened. At that time this team was too enthusiastic in bringing in lots of expensive players. And there are many other problems that make this club's financial problems worse. It was even reported that Xavi was fired because he revealed the club's financial crisis. But fortunately Barcelona has now managed to get the signature of a new coach by offering a salary that is not too large and below Xavi's salary. But I hope this club can recover, but it will take quite a long time. And perhaps selling the club is the last resort if things get worse.
