Definitely. He did exactly what you'd expect of him on an average day plus he smashed in a lovely free kick. Its more or less what we'd hoped he'd do regularly this season.
BTW I think the idea that a loss of pace or burst is Willians problems is just throwing out an easy answer. He hasn't been quick for quite a while, the big difference for me is his lack of getting in the box, thats not down to pace. He hangs around outside and I can only think its because he's been told to because at Chelsea he was often in the box taking shots and getting to by line, etc Even last summer that was true, he didn't just lose all his pace in the 3 weeks break between then and this season.
