Indeed, and he only started to lose possession towards the end of the game, when everyone was getting tired. The heat is ridiculous in Washington, so it's no surprise really.
I thought he did very well, and if he played like that all the time, I'd have no problem with him being our regular CM. A good varied range of passing, keeping possession and being sensible but also making longer, more difficult passes. He was also getting forward, which was nice to see.
