Bolton Wanderers have joined Madrid-based Unin Adarve, who play in the fourth tier of the Spanish soccer pyramid, in reporting Barcelona to FIFA following their signing of Marcos Alonso from Chelsea last summer.
The defender played for the two clubs earlier in his career and both claim they are due a development fee from his current employers, which they haven't received.
FIFA have already heard the cases put forward by Bara and Adarve but haven't yet reached a final ruling, says AS.
The current system deployed by FIFA means that a small percentage of any player's transfer fee must go to clubs he or she represented at youth-team level after the age of 12. Alonso spent the majority of his youth career at the Real Madrid academy but also turned out for Adarve, while he later left Los Blancos to sign for Bolton when he was 19, an age at which he still qualified as a youth player.
The English side, who now played in League One, two levels below the Premier League, now claim they are due training compensation, even though Barcelona announced the arrival of Alonso on a free transfer from Chelsea. Neither Bolton nor Unin Adarve believe that to be the case, however.
They believe Pierre-Emerick Aubameyang's departure to Chelsea and the arrival of Alonso at Camp Nou were part of the same deal and not two separate ones, arguing that the 12 million fee that the Blues paid for the Gabonese striker is significantly below his market value, which means that Alonso must also have been included in a cash-plus-player transfer.
