No its not, I dont think he is great, but him playing a winger is NOT something he can be blamed for (just like Eboue playing winger too isnt his fault), he is a box striker, and can play quite good there, and is improving more and more, even if iffy consistency in finishing, but even if he hasnt been bad as a winger (decent), I dont get at all why Wenger is still insisting on playing him as a winger. While you see RVP who has little presence in the box, being there, doing very little.
