Wigan are keen to sign the Oman international on a permanent basis after a season-long loan deal, during which he won the club's player of the year award.
Latics have made a third bid of ?3.7million bid for Al Habsi but Coyle is holding out for his valuation of ?4million.
Wigan are expected to come back with another improved offer and despite his eagerness to re-invest the money on new players, Coyle insists Bolton won't back down to ensure a quicker sale.
"We haven't shifted one iota, so Wigan have known since the very start where they need to get to," he said.
"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.
"The scenario is very simple and both me and the chairman have been very consistent - we have never put it out there that we wanted Ali to go," Coyle added.
"If there's business to be done, then it has to be done at the level we think is fair, to us and to Ali."
