If he was a finisher he'd be worth a few million.
Thats the clincher, if he could finish he would be playing a lot higher with his work rate and speed, he has the control too 95% of the time but his final ball is often poor, its improving but he really needs to work on cleaner striking of the ball in front of goal.
If he can learn that then he will be a very good player, hes improving but does still need some work in training. He has so many good attributes but he needs to add finishing or even better crossing to that to go further.
Bolton and Wigan saw something in him but couldn't quite bring it out.
A good striking coach should work with him, he could even learn some things from Doyle with his experience.
Cannot fault his attitude though no matter what, he has done well despite what a lot of fans thought or think of him.
With his pace he is always going to be pushed wide so if he can learn to cut inside and shoot consistantly, maybe even playing him on the left wing as we used to play the left footed Ritchie on the right wing so he could cut inside onto his stronger foot, the inverted winger, that could work too.
I am not entirely sure that Wellens sees him as an out and out striker though, his versatility could work against him being a regular.
