I don't think anyone is doubting his overall ability or how important he is to the team.
Given his quality, he 'should' be scoring more than he is. Last nights chance was just symptomatic of why he's not scored enough, given his skill levels and the positions he gets into.
It's frustrating because he's a great player but if he scored a few more, we'd be higher up the table. And before G chimes in and says 'yeah but if A N other player scored more, we'd be higher'...our two main strikers this season Gyo and Godden have 23 goals between them. The next most advanced player is O'Hare with 1. Then you have two defenders with 3 apiece, it's just a little frustrating.
We are better with him though, than without. Surely no one questions that?
