Some people will probably say that Ben Arfa HAS to be on the right, and i don'r agree. I think he's very good out on the right, no doubts about that, but we also forget that when he played in the position behind the striker/s he wasn't nearly as fit as he started to become when he got placed out on the right instead. Imo he didn't have the same confidence then either, i've played both positions myself and it's always easier to start on the right if you're not in form, there you can gain confidence more easily i think.
Wouldn't mind him in that position Tiresias, in a free role where he still can start from a wide position.
This would work a lot better as we'll have Santon and hopefully Debuchy to give us some width, we didn't have that when Ben Arfa played in the middle (unfit and no confidence as well)
