The Easter Road setback was Celtic first loss in nine games, and Lennon admits he will accept a similar display from his charges against Motherwell.
Celtic go into Wednesday's match six points clear of their opponents and Inverness Caley at the top of the table, while the team are still involved in all three cup competitions as well.
Lennon said: "We didn't need a boot up the backside. That was not a reality check.
"There was no complacency from what I could see. I would take the same intensity of performance and the desire.
"There was a real hunger to win the ball back, there was a real hunger to win the game, it just didn't drop for us.
"The players will be highly motivated for Motherwell. It is another big game for us.
"There are a lot of teams playing well and scoring goals in the SPL.
"Stuart McCall has done a brilliant job, with the squad he has got, it is underestimated sometimes, but they are very attractive to watch and they are a dangerous team."
