Rubén Pérez is a Spanish defensive midfielder known for his tactical discipline, tough tackling, and ability to recycle possession, currently playing for AE Kifisias in Greece. A product of Atlético Madrid's famed academy, Pérez made his first-team debut for Los Colchoneros and was once considered a future star. His career, however, has been defined by numerous loan moves across Spain and Europe, including spells at Deportivo La Coruña, Torino, and Granada. Despite not establishing himself as a permanent fixture at Atlético, Pérez built a solid career as a high-level midfield enforcer in La Liga and Serie A. He is a midfielder who does the unglamorous work perfectly, breaking up play and providing a platform for more creative teammates. His experience and know-how in the engine room are valuable assets for his current club.
