Journalist Gerard Romero reported via social network that Barcelona is experiencing severe economic problems and cannot find funds for transfers.
According to the source, the club has no money for new players and there are no available funds in the payroll. Barcelona managers will discuss the situation this week.
Barcelona recently signed 32-year-old former Manchester City midfielder İlkay Gündoğan as a free agent.
Last season Barcelona won the Spanish championship for the 27th time in history.
