Liverpool have Agger and Srktel tied down till 2016 so I can't see them wanting to put Ash in there. They seem to be concentrating on younger, cheaper players too for the most part. That said, if Man City go after Agger again I'd be a little nervy though. Arsenal have Vermaelan, Koscielny, and Mertesacker, and none of them seem like movers at the moment.
