Diego Costa's hamstring injury appears to be worse than first feared but Chelsea are still hopeful that he will be fit to face Arsenal at the Emirates Stadium on April 26th, reports The Telegraph.
The £150,000-a-week striker was forced out of the game against Stoke City after pulling up with the familiar problem. He struggled with the same issue earlier this season and once again against Hull City last month.
Jose Mourinho has already ruled him out of contention for the next two weeks meaning he will miss games against both Queens Park Rangers and Manchester United. However, Costa is desperate to regain fitness in time to face the Gunners.
Chance to win it
Should Arsenal fail to beat Burnley and if Chelsea can beat QPR and Manchester United then the Blues will have the chance to seal the title at the home of their London rivals. Even if they can't do it, a win against Arsene Wenger's men will all-but confirm them as the new champions of English football.
Costa, 26, has been key to Mourinho's team this season, scoring 19 goals in the Premier League and leading the chase for the Golden Boot. He wants to be part of the team that has the chance to kill off the title race against a major rival.
Chelsea's medical team will watch Costa closely over the next week and Mourinho won't allow him to train with the first team. Instead, the Spain international will focus on gym work with the club's physios.
Crunch time will come with the next scan where medics will decide whether or not Costa is fit enough to step up his rehabilitation. If he fails it is likely he will not be fully fit to face Arsenal.
Mourinho will not allow Costa to rush himself back after being fooled by him before the Stoke game. The striker convinced Mourinho that he was ready to be on the substitutes bench for the Premier League clash, but last just 12 minutes after coming on in the second half.
There is now a concern that Costa has sustained worse damage than initial feared and that he will need an extended break before playing again this season. There is also the possibility that Costa may have to undergo surgery in the summer if he fails to make a complete recovery.
