That is what Vitali was thinking. He wasn't happy. I thought initially he'd 'done' his knee. As in properly done it. But then he went and got up and started walking around at the end. He looked like he was really tired at the end, like he could just fall asleep. Or that he was really bored.
I suspected betting scandal would be mentioned, but the 'expert' commentator, McGuigan(?) seemed certain he was badly shaken by it.
