Am I the only person who wouldn't really want Sam Parkin back? With all this injuries he's had I'd worry that he'd lost a part of his game and wasn't as good. I'm not sure I'd want to risk the heroic status he has.
I'd say go for it. Okay so he's not done greatly recently but when he has played he has been in a team egtting relegated from the Championship. With decent support and at a slightly lower level I think he'd be great back here.
Of course there is only a minimal chance of it actually happening!
