Diego Costa still need 15 days to fully recover from his hamstring injury, according to Jose Mourinho. Costa once again scored for Chelsea in a 3-0 win against Aston Villa at Stamford Bridge. In the post match press conference, Chelsea boss Jose Mourinho revealed Costa barely trains between games and can only start one game a week.

Costa has scored eight goals for Chelsea this season helping Chelsea to sit comfortably at the top of the table. Chelsea play their next UEFA Champions League game against Sporting Lisbon in Lisbon and Mourinho has not confirmed if Costa is fit to start. Mourinho also wants Vicente del Bosque to drop Diego Costa for the upcoming international fixtures so that Diego Costa can recovery fully from his hamstring injury problem.

“A striker scoring goals is always nice for him and for his confidence,” said Mourinho after Saturday’s victory. “Especially for someone like him who is not training as he should because we are protecting him in certain situations so he cannot be at the top of his game. 

“He’s doing almost nothing [in training]; he’s resting and recovering from the tight muscle he has every time he accumulates fatigue.

“I think if he doesn’t go to the national team and stays here for 15 days just on treatment and recovering, making the muscle and the areas around the muscle stronger, he has the perfect chance to be top for Chelsea and [his] national team. 

“If he doesn’t have this period he will always play one game [but] the next is trouble. The muscle is tight; the muscle is in danger to rupture.

“We have to respect the decisions [of Del Bosque] because we can’t do anything [to stop him being called up].”
