The 43-year-old Northern Irishman was unveiled as Dougie Freedman's successor at Wanderers on Monday afternoon in what is his first job since he left the Glasgow giants in May.
After a successful four-year stint north of the border when he guided the Bhoys to three league titles, two cups and a memorable Champions League triumph over Barcelona, Lennon faces an altogether different task at a club anchored to the Sky Bet Championship basement.
"It's a huge challenge, a massive challenge and that's what I was looking for," he said.
"It's the stimulus of a challenge
Things went really well at Celtic but I felt I'd run my course
I had six months out of the game which I'd enjoyed but I started to get the itch again
Bolton have entrusted me with this opportunity and I'm very grateful for that."
