Diego Costa: Atlético striker does extra training in Fernando Torres' gym
The former-Chelsea striker is working towards match fitness for January, when he will be able to be registered for Diego Simeone's side.
Diego Costa will not be able to pull on the red-and-white stripes of Atlético Madrid until January, as a result of the club's transfer ban. The Brazil-born Spain international is working at full capacity to ensure he is match-fit when the time comes to make his second debut.

Costa is working at the Cerro del Espino stadium, which Atlético reserves share with lower-league side Rayo Majadahonda, with notoriously demanding fitness coach Profe Ortega.
