I take your point but think he adds as much going forward as you can reasonably expect from a typical winger at this level to be honest. Adds threat in behind with pace, quite regularly beats his man when he fronts him up, and has pretty decent end product. I can’t think of another winger who’s directly contributed to more goals this season off the top of my head (edit: for OUFC). And he’s generally fine covering back, though no more than that.
I think his issue is he consistently fades badly after about 60 mins. Regularly looks shagged and stops chasing back at all. Didn’t affect us too badly today but against Bolton especially it probably should have lost us the game. He’s probably a victim of being overplayed at the minute, as we don’t have any other option for the RW. He was a real threat off the bench earlier in the season and, while I think his defensive play has improved as a result of consistent starts, I think he could do with some rotation.
