can they cope?:Chelsea likely to be without Costa for three weeks

Jose Mourinho might be without top goalscorer Diego Costa for up to three weeks because of injury.
The Spain international has been struggling with a hamstring complaint from his time at Atletico Madrid and reports claim he pulled up in Chelsea training this week.
Costa is being treated by medical staff at the club, but there is a serious fear that he might not return quickly – a situation which will leave the Blues with a striker crisis.
Didier Drogba is currently battling with an ankle injury, leaving Loic Remy as the only fit striker the Blues have, ahead of Saturday’s trip to Crystal Palace.
Mourinho however refused to comment on whether Costa will be fit to play at Selhurst Park.
