Jose Mourinho: 'Diego Costa doubtful for Crystal Palace trip'

Chelsea manager Jose Mourinho has indicated that striker Diego Costa is struggling to be fit for his side's match with Crystal Palace.

Costa featured in both of Spain's Euro 2016 qualifiers during the international break, despite needing to manage a hamstring problem since the start of the campaign, and Mourinho has revealed that the forward was back at Stamford Bridge for treatment on Monday morning.

The 51-year-old told reporters: "The Spanish team played in Luxembourg on Sunday. I gave [the Spanish players] two days off so they have to report to train Wednesday at 3pm.

"Diego was here Monday at 9am so you can imagine how strong he was."

The 26-year-old has scored nine goals in as many games in all competitions for the Blues.
