We haven't seen nearly enough of him to properly judge him.
The odd 5 to 10 mins here and there is not enough to play yourself into form in a new team. He needed a run of games to do that.
Given how poorly other forwards have played this season and also given our lack of goals at times, him not playing more is a bit hard to fathom.
He does seem to have an eye for a goal and, unlike others, does like to get a shot off early - which I'd like to see more of.
