Atletico Madrid fitness coach Profe Ortega has enjoyed winding up Diego Costa during their grueling sessions this week.

Marca says Costa needs to return to full fitness and Atletico Madrid have set their renowned fitness coach Ortega loose on their new signing.

The striker hasn't played a competitive match since June and is being put through some intense fitness sessions, which have provoked many digs and humorous comments between the two.

"I don't know where you've come from," Ortega even joked to Costa during one session in which the player was struggling with a balance exercise.
