Celtic boss Neil Lennon has admitted that he has thought of taking on a new challenge in his managerial career.
The 42-year-old has been in charge of the Glasgow giants since 2010 and has won the league title and the Scottish Cup twice each.
"Well, yes," the Daily Mail quotes him as saying when asked if he has wondered how much further he can take Celtic. "It's not been as good a season as last year, but that's okay because I never thought we could emulate last season anyway.
"I think you know instinctively when there is a cut-off point. Whether mine is here yet or not, I do not know. I do speak to Gordon [Strachan] about it but it's not high on my agenda at the minute.
"This is a great job. Like everything else, you have good days and bad days. The good days are good, the bad days are horrific. That's part of the excitement - you have to be a bit of a masochist to do this job.'"
Lennon added that he does not want to leave Celtic and move to another club, only to find himself get fired.
"I don't fancy looking at wallpaper, carpets and stuff like that for however long because once you're out of a job, it's difficult to get back in," he said.
"One - it is good money, it pays the bills and keeps the clothes on the kids. And two - you can be forgotten about very quickly. There are good managers out the game for two, three years who apply for jobs everywhere and can't get back in.
'You've got to be careful. I'm not saying I'm going to leave here and walk straight into another job. I haven't made any designated plans for that, either. I'm not in any rush just yet."
Celtic are currently 18 points clear at the top of the Scottish Premiership table.
