I'd play Coquelin, Arteta and Ramsey with Özil in a free attacking role probably. We need to rethink our formation next season, but at the moment it just seems easier to adjust Özil's position a little bit than to play Ramsey on the flank. I don't think it would make him less influential.
We've delegated more of our game to the flanks right now anyway thanks to Monreal and Bellerin, so what we really need from Ramsey is someone who passes and runs between the lines. Someone said in the other thread that Ramsey would have scored if he had gotten the chances Cazorla had against Chelsea, and I think there's truth in that. It's not a slight on Santi, but Ramsey really excels there.
