Financial problems have really hit Barcelona back in terms of business and club finances. They have to really adjust spending and income to compete with other teams in La Liga, but of course this will definitely take a lot of time and thought.
Maybe Barcelona can get another big investor who will support them financially and solve some of the problems, but it's definitely not going to be easy. I'm not sure if Barcelona should consider selling their club to be owned by someone like Chelsea, Manchester City, PSG, Newcastle or some others, but surely it will help them solve their financial problems.
Barcelona has financial problem until last rumor about not extended Sergio Busquets contract although have been most most influential and important player for Barcelona due difficult for higher salary have to pay. La Liga teams have different rules than other European league teams regarding the ownership or shares that can be owned by foreign investors, it seems that foreign investors cannot have a majority stake in a La Liga team and I think this situation is difficult for Barcelona to be able to get investors like Manchester City or PSG.
Complicated with financial problem faced by Barcelona last several season, but if can winning La Liga tittle this season can be great achievement and they have chance for improving with financial problem for next season.
