We're only awful at set pieces. Sort that out and we are almost impregnable. The slight worry is the lack of goals at the other end. We've scored half as much as we had by this stage last season. But Villa at home might give us a chance to address that. And it's not like United and Chelsea are any better. Nothing to be too unduly concerned over that a couple of heavy victories and a two more clean sheets in the next few weeks won't put right.
