Sporting Portugal have demanded €105m from Atletico Madrid for the transfer of Gelson Martins, report A Bola. The Portuguese winger joined Atletico last summer in the wake of a mass exodus at Sporting.
Several Sporting players were attacked by supporters last season after they managed to break into the training ground. Martins was one of the players to terminate his contract before he signed on a free transfer to Atletico Madrid.
Sporting, however, claim that they have rights to a transfer fee for Martins and have now moved the case to the court. According to the reports from Portugal, Sporting are read to demand €105m in compensation.
