Flying slightly under the post-Swansea storylines radar are Diego Costa and his dodgy hamstrings. As you might have guessed, that's probably a good thing.
"He did very well, and again the second half is very difficult because it was a big difference -- one player less and a lot of effort and even so I was not expecting him to resist for 90 minutes. But because we wanted to try to get a goal we went with him until the end and it was very important and new for us that he played for 90 minutes with such a physical performance."
"He is happy with the reaction. He is okay, happy, he is very happy and with the reaction with his body after such a hard game."

There was one particularly scary moment, when Costa and Jonjo Shelvey came together over a 50-50 ball, but both eventually walked away unscathed. Costa, may have only taken one shot, but he looked lively and involved in general, made several decent runs, took out goalkeeper Fabianski once, and was unlucky to not have won at least a free kick off Ashley Williams at the end of the match and maybe even a penalty when Federico Fernandez cleaned him and the ball out for a corner much-much earlier.
Diego was not back to his best quite yet, but he and his hamstrings seem to have survived for another week. We'll need them all this coming weekend against Manchester City.
