Lennon emerged as a candidate for the Sunderland manager's job following the sacking of former Hoops hero Paolo di Canio. It is the latest high-profile position the Northern Irishman has been tipped to land - last season he was one of the favourites to replace David Moyes at Everton.
Celtic's success in Europe's premier club competition last season, when they beat Barcelona to qualify for the last 16, saw his stock rise south of the border. However, Lennon has stressed he is completely committed to the Scottish champions - who have announced a pre-tax profit of £9.74million for the last financial year - and is looking forward to their impending Champions League matches.
He said: "There's nothing in it for me. I have a great job here and I'm very happy with the way things are going.
"Would it be difficult to walk away from this club? Of course. Plus I've got good players here. It would be a lot to give up and, to be honest, it's never really crossed my mind.
"These are very exciting times for the players. There are opportunities there for them and it isn't just one game against Barcelona.
"We have the double-header against Ajax to come as well as Barcelona away and then Milan at home. There is so much to look forward to.
"It's also important that we keep our momentum going domestically. We need to stay in form and confident and that is what we are focusing on."
Lennon watched Champions League rivals Ajax lose 4-0 to PSV Eindhoven in the Dutch Eredivisie on Sunday and admitted the scouting mission had given him "food for thought".
He said: "Maybe Ajax had a hangover from the Barcelona game but I can't see that form lasting. They are a very good side. Bojan, Fischer, Sigurdsson, De Jong are all quality players in attacking areas."
Elsewhere, Lennon has banned all talk of Celtic landing the treble ahead of the home League Cup encounter with Morton this evening.
He said: "I haven't given it a minute's thought, really. Winning the double last season was great but the treble is such a different thing to do.
"We're perceived to be far ahead of everybody else but you still have to go out and win the games.
"We saw last season that all it takes is one off-day - or even a half-poor performance - to lose out so I haven't thought about it.
"Our short-term objective is to beat Morton, forge away in the league and try to finish second behind Barcelona in our Champions League group."
Meanwhile, Uruguayan striker Nicolas Mezquida has joined the Hoops on trial.
The 21-year-old had most recently been on loan from Centro Atletico Fenix to Rampla Juniors in his country's second tier, but is now a free agent.
Mezquida began his senior career with Penarol and spent time on loan in Norway's top flight with Brann and Lillestrom.
The former Uruguay youth international moved to Primera Division rivals Fenix in 2012.
Bundesliga outfit Schalke 04 had an option to buy a teenage Mezquida during his time at Penarol.
However, a permanent move to Germany did not materialise.
