Diego Costa forced himself away from Chelsea and return to Atletico Madrid only after three seasons at Stamford Bridge, but will be ineligible to play until January due to their transfer embargo.
Costa made 59 goals in 120 appearances, two Premier League titles. He will not be playing at Atletico at this time but is working on his fitness as he prepares to play for them.
“Diego is a huge player. He scores a lot of goals and important goals,” Luis, who returned to Atletico after a single season at Chelsea in 2014-15, said:
“It is frustrating seeing him playing like an animal, but he can’t play. It’s just a month until he can play with us. He’ll help us a lot.
“He came back to Atletico because Chelsea couldn’t keep him because it’s his desire. He really wanted to come back to Atletico.
“He knows the club, he knows the way we play. He has already adapted.
“I know it was difficult times for him and for Chelsea. Now everybody’s happy. We want to see him play and happy again.”
