Lennon has been out of work since leaving Bolton Wanderers in March and is second favourite for the Bhoys' gig with some bookmakers.
Former Celtic manager Neil Lennon has reiterated his interest in a return to Parkhead this summer in an interview with Talksport on Monday.
Lennon managed the Bhoys for four years until May 2014, walking away having delivered the club's third straight Premiership title.
The Northern Irishman was hired by Bolton Wanderers five months later but, hampered by financial difficulties, was unable to halt the Trotters' slide towards the third tier of English football.
Lennon eventually left Bolton by mutual consent in March with the club's relegation confirmed soon after.
Despite securing two more titles in Lennon's absence, the 44-year-old's Celtic replacement Ronny Deila was unable to replicate his success in Europe and will leave the Bhoys this summer.
Lennon is currently second-favourite to succeed the Norwegian with some bookmakers, behind Brendan Rodgers and ahead of David Moyes and Paul Lambert, his former midfield partner at Parkhead.
Last month, Lennon told BT Sport's Fletch & Sav show: "If the board wanted to speak, then there is no question about the interest," and he has now reinforced that statement on Talksport.
Asked if he would find it difficult to say no to Celtic, Lennon replied: "Of course. It’s a great job and a great club.
"I had a good four years there the first time (as manager). It was 15 years there on and off. It was a big part of my career and my life.
"So yeah, there would be a definite interest (from him)."
And the Lurgan-born boss confirmed he'll wait for the season to die down before taking on a new role.
"There’s no rush," he added. "When I finished in March I didn’t think going straight back in was the right thing to do.
"I’ve had a lot of media work which has been brilliant and so I’ll wait and see what happens in the summer."
