Celtic boss Neil Lennon says he'll only leave for a step up.
He said: "If I was going to leave Celtic I would go to one of the big clubs but they're all on lock-down pretty much with the good managers they have already.
"It's difficult to break into that pack anyway.
"Football is very unpredictable, a week is a long time in football never mind a season.
"We'll take stock of things and chat about things at the end of the season.
"The board have been brilliant with me, they've never put me under any pressure and never interfered in anything we're trying to do so I'm very lucky to have people like that behind me."
