Chelsea have reportedly been handed a major injury boost after it was revealed that striker Diego Costa could recover by this weekend from the hamstring strain sustained on international duty.

The Spanish international striker complained of pain following Spain's loss to France and was subsequently pulled off the team after undergoing a scan in Madrid. It was feared that the Blues forward will be out for at least a month with his current injury.

The 25-year-old striker, who has suffered from niggling injuries since the end of last season, was a doubt ahead of the Everton game two weeks back, but recovered to play a starring role and is Chelsea's form player having scored four goals in three matches so far.

Following the medical assessment and scan by the Spanish squad doctors, Costa has returned to London and undergone more tests under the supervision of the Chelsea specialists at their Cobham training base, which has revealed no extensive damage.

It is now believed that the former Atletico Madrid striker could be available for Saturday's top-of-the-table clash against Swansea City at Stamford Bridge.

According to the Daily Mail, Jose Mourinho is monitoring the player and will make a late decision on whether to include his star striker in the squad to face the south Wales club.

The absence of Costa will be a massive blow to Chelsea, but one that will be softened with the knowledge that they have Loic Remy, who was signed at the end of the transfer window as a replacement for Fernando Torres.

The French striker will not be first choice once Costa returns and will be keen to take this opportunity to impress his new manager. Remy's confidence will be high after scoring the winner in the friendly against Spain last week.
