"When you do have an injury, it's sometimes difficult to concentrate," said Murray afterwards."Against someone like him, you need to play every single point, concentrate from every single point to the last. You can't just throw games, hope to hang onto your serve. You need to play every single point to put pressure on him.""Yesterday at the beginning of the second set I felt something, but I managed to play through it," Murray added."This morning I was hitting, warming up fine. I went to hit some serves; I couldn't serve.""I thought it was a good match, but I think I can play better," said Murray. "It's good to know you're able to play at a similar level to what he does on the clay. To win against him, you need to be able to do that for three-and-a-half hours, four hours."The matches that he's lost on clay the last few years have been normally long ones. He's the best player in the world for a reason.""Certainly I'll have an MRI scan, maybe tomorrow," said the Scot. "You sometimes get like a bit of bone basically that has fallen off."It sounds worse than it is, but it's basically floating around in the joint, so every time I bend it, I get of a lot of, like, clicking. It just feels really bruised because I obviously had a couple of injections. There's blood and stuff going in there."It was good because I managed to play, but I would have liked to have finished the match a bit better."
