Manchester United legend Roy Keane won't rule out taking the Celtic job in the future.
Aston Villa coach Keane rejected the Hoops post over the summer.
"I think you have to be opened minded. I've tried to explain the situation. I was probably about tenth choice. I've heard on the grapevine that one or two other people had turned it down which wasn't an issue for me but at the time the negotiations didn't go the way I'd have hoped they would have gone, but I'm not sitting around waiting for people to lose their jobs.
"I have to be careful with what I say because there's a new Celtic manager and you want to wish him well, so I don't sit back and think 'if these come calling'. With the madness of the game you don't know what's around the corner at all and at the moment I'm just focused on working with Martin (O'Neill at Ireland) and the rest of the staff and the players and getting used to my role at Aston Villa.
"I'm not sitting around waiting for managers to lose their jobs. I'm not that type of personality. I honestly hope all other managers do well, but of course the game doesn't work like that and managers lose their jobs, but I'm not sitting around waiting for the phone to ring I have to say."
