He was excellent against Villa but I wouldn't be too revisionist on his impact.....he still only scored or assisted 1 in the previous 24 (and none in the previous 12) before that game, which is not really acceptable when you see how prolific Barnes, Gayle, and Rodriguez have all been as part of the front 3.
When he's on it like Saturday or against Leeds he can be a real asset....but unfortunately those games don't come often enough, and through no lack of trying. When Phillips is back i'd hope he'd feature in the front 3 with Gayle and Rodriguez.
