Diego Costa may be glad that he has three months to get up to speed at Atletico Madrid - given the high intensity of their fitness sessions on the training field.
The former Chelsea man has completed his move to Madrid, but due to the club's transfer embargo will not be able to feature until 2018.
That gives him a few months to return to full fitness, and if the club's latest video is anything to go by, Costa may well be glad for the extra time.
The notorious Oscar 'Profe' Ortega - whom Costa knows from his initial time at the club - leaves the striker looking exhausted in their latest drills, taking place away from the rest of Diego Simeone's squad.
