In the wake of the Hoops' Champions League last-16 exit on Wednesday night at the hands of Juventus in Turin, the prospect of the Northern Irishman attracting interest from other clubs on the back of such a remarkable run was mooted, with chief executive Peter Lawwell admitting his manager could be in demand.
However, ahead of Saturday's SPL clash with Ross County in Dingwall, Lennon said: "It (speculation) makes no difference to me.
"I am the manager of Celtic and I am one of the privileged few who have been lucky enough to do this job. I enjoy it, I love what I do.
"I can't stop speculation about players or myself but at this current period I am Celtic manager and I don't see any reason for that to change in the future.
"Does it flatter you? It just means that you might be doing a decent job along the way."
