The Mali striker has yet to hit the back of the net in 10 games this season.
Allardyce said: "He hasn't scored a goal and that's what they see.
"In the end he was very good on Saturday, very, very good. I think they are intelligent enough to have seen that.
"Whether there are one or two that weren't quite so keen on him playing by the time he finished his contribution on Saturday... but we completely dominated and outplayed the opposition!"
