I totally get criticism that he should be doing better, particularly with the chances he's getting but i'm not buying that he offers absolutely nothing.
I will say I don't think he should be starting two games in a week though.
I think there's some fair points there, however, he's here now, as far as I can see his attitude is fine, i can not fault his work rate or desire despite what some people argue. I don't think he should be playing two games in a week but my point is that I don't think he's finished and for me he's our first choice striker until the season ends.
On another point, Like Giggs I can see him playing at a high level until he's 39/40. Unlike Giggs though I wonder if his ego will let managers have an easy ride in deciding what games he should play.
