The manager insists the club will not reduce their £4million asking price for a quicker sale.
"We haven't shifted one iota, so Wigan have known since the very start where they need to get to," Coyle told The Bolton News. "If they are edging closer, then they are only doing that because they have known what they have to do from the outset.
"If they get to a place where we're all happy then there might be some business done. Until they do that, there's nothing to discuss."
