FC Barcelona potentially face further legal headaches.
According to Diario Vasco, Claudio Bravo has launched a suit against Barcelona and Real Sociedad over the terms of his transfer between the clubs last summer.
The Chile goalkeeper is claiming 1.3 million euros, which corresponds to 10 percent of the 13-million-euro transfer fee agreed between Barça and la Real.
Barcelona have expressed their surprise at the decision and are expected to meet with the keeper's representatives in the coming days.
