I suspect that there might be exploratory talks if this is true. Sounds like it might be a rush at this stage but Wrexham were after somebody else who's fallen through.
I thought I'd seen it a few months ago. I don't know whether it's correct or not...

Woolfenden's not had a lot of football in the last year. I see him as another L1/lower champ player like a few is out team/squad but that seems to be the market that we're in. Would strengthen the squad.
