that sounds like a long shot IMO. i can only think of washbrook who they might accept. who else would they want to take?! we can't afford to lose any other forwards...
if warrington have been wanting to sign westerman for a while now then they could have offered richie mathers since he's ended up at cas anyway!!
I think Mathers was off contract anyway so that wouldn't have worked, If Wire want him they can just buy him, decent player but as others have said all the money we have needs to be spent on a halfback, or we won't finish in the top six in my opinion.
