The Scottish giants have an unprecedented grip on the Premiership in their country.
And they have been crowned champions for 2019-2020, as the league is cancelled for the rest of the season due to COVID-19.
"To be sitting here now as the manager of the nine in a row, and having played a huge part in that, fills me with so much pride," Lennon told Celtic TV.
"It feels wonderful and I'm so proud of the players. It's an incredible record and to be part of that is something very special, and I think it's thoroughly deserved as well.
"It's the best, no question it's the best and I've enjoyed the season immensely. I enjoyed the European campaign and winning the League Cup and I enjoyed working with the players every day, I enjoyed working with my staff.
"Whether you look at the first half of the season or the second half of the season, we've played some brilliant football throughout, and then you throw in the European campaign, you throw in the League Cup. A lot of that gets overlooked with all that's been going on around Scottish football of late.
"The style of play pleased me, the amount of goals pleased me, and we had massive contributions from numerous individual players as well."
