Tbf the guy is as solid a club journalist source you can get. 25+ years working as chief sports reporter for BHAFC news- he's gonna have some pretty strong sources. Given the quiet from all of city's reliable journalists I'd suggest there isn't much reason to disagree with him. All that has been said is its unlikely City would go to 50m.
I think if he's saying 50m or nothing then that's probably the case. Atm this thread is clinging to comments by Weir and Potter that could mean nothing and the hope of a second bid that is yet to materialise.
I'm not sure how you can be confident on this one atm.
