Atletico Madrid have confirmed the signing of Gelson Martins on a five-year contract until the summer of 2023.
Los Rojiblancos announced Martins as a free transfer after he was one of the stars to terminate their contracts with former club Sporting CP following an attack from fans at a training complex, per the Guardian's Ed Aarons.
Football Espana referred to recent reports suggesting Sporting were confident of securing a €45 million (£40 million) fee for their player, who was linked with a series of major European clubs following the fallout in Lisbon.
