The Spain international suffered a recurrence of a hamstring injury on April 4 but is edging closer to a comeback and may face the Gunners in the top-of-the-table clash
Jose Mourinho has revealed that Diego Costa will return to training with the rest of the Chelsea squad next week and is in contention to face Arsenal on April 26.
Costa, who has scored 19 goals so far this season, has not featured for the Blues since sustaining a recurrence of his hamstring injury against Stoke City earlier this month.
The Spain international will again watch on from the sidelines as Chelsea welcome Manchester United to Stamford Bridge on Saturday, but Mourinho says he could be involved at the Emirates Stadium in nine days’ time.
“[Costa] is progressing very well. I think he has a chance for the next weekend,” he told reporters.
“Our target was for Diego to play in the last four matches. Arsenal is the sixth match to the end so if he doesn’t play [against] Arsenal or Leicester [the following Wednesday], it is not a problem.
“He starts training with the rest of the squad next week.”
Chelsea sit seven points clear of the Gunners at the top of the Premier League and have a game in hand on Arsene Wenger’s side.
