It's not just about missing sitters though.
Again I want to point out that i'm not slating him here or saying he can't improve on this, but I think people are being a little too forgiving about the lack of goal threat in general.
If you don't recall him missing any chances, and he's only got 6 goals, then that tells it's own story I think, that he needs to improve on his ability to get chances. There was an example in the second half on sunday where Sigurdsson teed him up at the edge of the box and I think the entire ground expected him to hit it. He didn't though, he took a touch, maybe 2, and then passed it. It's that type of thing that he needs to work on, it was a chance but he didn't even get a shot away. It's all very well lauding him for running round when we're winning 4-0 but if he does that at 0-0 we're all going mad, hence you remembering him missing a chance at Fulham when we lost but not at West Ham when we won. The other players won't always score the goals we need, he has to be able to get his fair share too, and I think that's all anybody is saying in here.
