He's a winger. Started off as one anyway and then Wenger moved him to left back because he wasn't good enough to play as a Wenger type winger. He needs to work on his delivery cause he's been putting in crap crosses since the season started. Compare that with Jenkinson..that kid can delivery. No idea on what is happening with Santos. Wenger may have given up on him as a wingback and because in the pre season games and one or subs, he's played higher up field as a winger. I hope not because if he gets used to the Prem and how to defend, he'd be an ideal first starter. But defensive discipline must take priority. I hope we get to see Santos in the Carling Cup at least.
