I'd disagree with this. I think the main obstacle for Shay moving to Arsenal would be the fact that Arsene Wenger doesn't rate him. He came out and said
he wasn't interested in signing Shay when he was leaving Newcastle citing that they weren't looking for a keeper when they clearly were, and he has come out again saying that
he's not interested in signing Shay from Manchester City citing Shay's high wages and then admitting in the same breath that he doesn't know how much City's keepers earn.
I think Shay is an amazing keeper, and is worth maybe 10 points a season, but I really can't see him ever moving to Arsenal while Wenger is there.
