The only card was the one he was duty bound to show, Khazri's hand ball. Overall much better than the 'look at me, I'm in charge' sort of display you get from some of the more senior refs, such as Prattenberg..
Sunderland might feel hard done by; he gave us more of the benefit of the doubt.
He kept his card in his pocket, which is good to see, though there wasn't much fire to cause booking opportunities. Just the handball.
Overall, pretty decent I'd say.
