The under-fire Celtic boss could lose his job if Celtic loses at Kilmarnock in the last-eight of the Scottish Cup.
He said: “Do I worry? Why should I worry? Worry about what? I have more to concern me.
“I’m here to build a team and do a job. You’ve got the wrong guy. It doesn’t impact on my life.
“I don’t like the idea of me telling you that because I see your headlines and you ask me leading questions so you can spin them round.
“I ask myself, are we 13 points less of a team than Rangers?”
