On Friday Atlético Madrid had their penultimate training session before their trip to Barcelona, and the important news for 'Los Rojiblancos' is that Radamel Falcao returned to working with the squad after spending Thursday working on his fitness.
The Colombian, who scored five goals last Sunday against Deportivo La Coruña but was complaining of sore muscles on Thursday is now certain to start against Tito Vilanova's side.
Adrián López, however, sat the session out after suffering an ankle sprain during Wednesday's Copa del Rey tie with Getafe and will play no part in the game at the Camp Nou. The forward joined the injured Cebolla Rodríguez in the gym.
Simeone looks set to field the same 11 that lost 2-0 to Real Madrid two weeks ago, except for one change - Filipe Luis, who was injured on the day of the derby, will replace Cata Diaz at left-back.
Atlético's starting line up is therefore likely to be: Courtois; Juanfran, Miranda, Godín, Filipe Luis; Mario, Gabi; Koke, Diego Costa, Arda; Falcao.
