Chelsea striker Diego Costa admits he's still carrying a hamstring strain.
Costa's hamstring issues date back to last season, where he was hauled off in the Champions League final after just 10 minutes after weeks of struggling with the injury.
And despite the concerns over his fitness, the striker insists he is on the road to a full recovery.
"I am still carrying some hamstring discomfort, but every day I feel better," he said. "The truth is that over the past week I have worked fine.
I suffered an injury with Spain and could not play against Macedonia (two weeks ago). It was a shame but then during that week I was treated and could play [against Swansea).
"I'm working to get the best physical condition soon. The games we have now, almost every three days, will help me to get fit."
