The Oman international is currently at near-neighbours Wigan where he has deposed former England goalkeeper Chris Kirkland as first-choice. Latics boss Roberto Martinez appears keen to keep Al-Habsi, who is 29 later this month and has two years left on his contract at the Reebok Stadium, but his form this season has alerted other clubs.
"If a bid comes in we'll sit down with Ali and his advisors and look at it," he told the Bolton News. "We can't really talk about it until it happens."
With Jussi Jaaskelainen a permanent fixture for Wanderers, restricting Al-Habsi to just 10 Barclays Premier League appearances since his arrival in 2006, Coyle appears content to let the player move on.
He added: "We know he's been playing well but we knew he was a top goalkeeper when we loaned him out.
"He needed to play and it was a great deal business-wise for the club and it allowed Ali to play Premier League matches as well as enabling us to promote Adam Bogdan, who is also an excellent keeper.
"It was a win-win situation for us. If a bid comes in January, we'll look at it, and do the right thing for the football club."
