Lennon's team travel to the Granite City one point above Craig Brown's men, who have only lost once in the Clydesdale Bank Premier League since their late 1-0 defeat at Parkhead on the opening day.
The televised midday game has captured the imagination in the north east of Scotland with Aberdeen having the chance to leapfrog Celtic and leaders Hibernian and go top of the SPL, even if it might only be for a matter of hours.
Lennon grew up in an era when Alex Ferguson's Aberdeen dominated Scottish football.
"Obviously I remember that great Aberdeen team, and the highlight was the Cup Winners' Cup final against Real Madrid," the former Northern Ireland international said.
"I remember sitting in the house as a boy watching it and jumping up and down because it was a Scottish team that were doing it.
"They had a great manager who has gone on to unbelievable things in his career. Gordon Strachan, Mark McGhee, Eric Black, Alex McLeish, Willie Miller, Jim Leighton, I can rhyme the team off near enough.
"They were an exceptional team in exceptional times. I remember going to a (Scottish Cup) semi-final I think in '83, Celtic-Aberdeen, and Aberdeen won 1-0. I was only a boy and it was one of the first Celtic games I went to see."
After the collapse of Rangers, Celtic were generally expected to surge well ahead in the title race but they have faced a challenge at home from Aberdeen and Hibs, teams who have struggled in recent years, while exceeding expectations in the Champions League.
"I think it's very healthy for Aberdeen," Lennon said. "I'm sure there will be a really good crowd. They have recruited well in the summer.
"Craig's very shrewd and obviously with Archie [Knox, Brown's assistant] there they have great experience in the background. And they have been pretty consistent this season, which is something you can't throw at Aberdeen over the last few seasons.
"It will be a good atmosphere, you'll have two big clubs in Scotland going at it and we'll not be thinking about Benfica until two o'clock tomorrow afternoon.
"It's an important game for us. Our league form recently hasn't been great. It's not a major concern for me but it's a game where we can set a marker down."
Lennon had prepared a response to those criticising his side's SPL form, which has seen them pick up two points from three games and often struggle around the European fixtures.
"There are people casting aspersions and saying we are being complacent because there is no Rangers," he said.
"For some players tomorrow will be the 30th game of the season already in competitive games and internationals.
"I have done a bit of research. In Germany, Borussia Dortmund are 11 points behind, Ajax are nine points behind, Real Madrid are eight points behind.
"A lot of teams are struggling to compete in both. AC Milan are 17 points behind, Malaga and Valencia are double figures, Montpellier, the champions of France, double figures, Arsenal 11 points.
"We are two points behind with a game in hand. There are a lot of other clubs who aren't top of their respective leagues so we are there or thereabouts so that's why I don't think there should be too much negativity being thrown at us. We are not doing too badly considering the workload we have had."
Lennon will come up against a familiar opponent tomorrow in Niall McGinn, who has scored in seven consecutive SPL games after being converted from a winger to a central striker since his summer move from Celtic.
"He has done very well," Lennon said. "I think scoring the goal for Northern Ireland (against Portugal) gave him a huge shot of confidence and he has been a very consistent goalscorer in the games after that and he will obviously be a threat tomorrow.
"He has pace, he is far better running on to things than playing with his back to goal so he probably dovetails quite well with (Scott) Vernon.
"I have not really seen enough of Aberdeen to really comment on that but the fact they brought Jonny Hayes in and the emergence of the young lad (Ryan) Fraser, and they have good experience as well, so that is why they are up there challenging."
Gary Hooper, Thomas Rogne and James Forrest remain missing for tomorrow's clash at Aberdeen but Lennon is hopeful they will make the flight to Portugal on Monday for Tuesday's Champions League clash against Benfica in Lisbon.
Lennon also hopes to have Scott Brown fit as his skipper fights an ongoing hip problem while fellow midfielder Joe Ledley is looking to shake off a knock he picked up in last weekend's draw with St Johnstone. Lassad Nouioui returns after a groin problem.
Speaking about the Pittodrie clash, Lennon said: "Gary won't make it. We are hoping he will start training on Sunday. Lassad is back in the squad. Rogne will hopefully train on Sunday.
"Forrest, at first we thought it was a hamstring strain, but it looks like he has damaged a nerve. We are hoping that will settle down and he can travel with us on Monday.
"Brown and Ledley are doubts for tomorrow but they should make Tuesday."
Hooper has been missing with a hamstring problem while Rogne has a calf injury. Left-back Emilio Izaguirre is out for about another month with a hamstring strain.
