Most of his (almost all, actually) goals in that one goal-scoring streak last season where after 80' when games tend to be more open. Playing for Everton is completely different than for United, I think you'll agree with that at least. He's good, just not great imo and a bit too one-dimensional, but maybe he'll adapt to the different playing style. What he has shown for Belgium suggests he can score goals for you (and definitely will) but won't offer enough in the general play and build-up, is what I think, what makes him a frustrating player a lot of times.
That was quality yeah, and I was as happy as the next man. I never said he was awful or something like that, did I? Just not top quality. I think that's exactly the kind of things he needs to be doing for United if he wants to succeed there, but he doesn't score goals like that often enough imo.
