Chiellini of Juve is a quality right back. Micah Richards looked awesome for Man City v West Ham, but he's young and he's homegrown and has already gained a reputation for himself, so he would cost quite a bit I reckon. I wouldn't even consider Bardsley! We are trying to make the step up here folks.
Edit: Actually, scrap Chiellini, now that I think about it, he's more of a left back right?
