The 21-year-old has been out of contract at Newcastle United and rejected the Magpies offer of a 12-month contract.
The on going transfer saga has left the Scotland Under-21 international just training at the Reaseheath Complex while both teams try and sort out a valuation for the midfielder.
An initial fee believed to be £60k was rejected and now believed to be twice that the amount but it seems the Magpies are holding out for more from the Railwaymen.
Alex boss Steve Davis told the club's official website: "Our third bid for Brad was rejected by Newcastle, so we will have to look at our options and decide our next move.
"I think we have made them a very good offer, especially for a player who has not had a lot of first team experience. In fact it was us taking him on loan last season that gave him his first taste of that experience.
"We would still like to sign Brad and give him a chance to play competitive football, so I'm sure the club will go back in with a final offer. It won't be too much more than what we have already offered because I think we have offered what we think he is worth.
"If that is rejected then we would have to decide whether to go into a tribunal situation, where it can be risky, or we decide that we have taken it as far as we can and the deal is finished."
