Chelsea manager Jose Mourinho has given his backing to the club's medical department who gave an all-clear to striker Diego Costa before he limped off with a hamstring injury against Stoke City.

Speaking in a post-match conference, Mourinho insisted that the striker was fit to play following medical tests prior to the match. "If the medical department decide to take four weeks, it wouldn't happen [to play him]," Mourinho told reporters.

"But no way am I upset with my medical department and I am not unhappy with the will of the player to try and help the team.

"From all the scans two days ago, the muscle and image was completely clean. The player trained twice at 100%. He did much more in training than he did in the match. The medical department do fantastic things for us."

Mourinho also confirmed that the former Atletico Madrid star will be out for a minimum of two weeks: "For sure a couple of weeks minimum. Let's see what happens."
