The thing is, we're 3rd in the league with him playing...why rock the boat and drop him? Him and McNulty seem to be a bit like the Heskey/Owen combination. No one liked Heskey but he was the perfect foil for Owen. McNulty is on fire at the moment...keep things as they are.
And granted Heskey did score some goals but mainly when he was the main striker, not playing behind Owen.
When Biamou eventually gets one, I reckon it'll be a big monkey off his back and his confidence will rocket. Just needs that one to go his way.
