"I'm delighted. We played well and scored three goals and created a lot of chances," Sky Sports News quotes Lennon as saying.
"Hopefully we have a clean bill of health. It was a sticky game for us and we dealt with it very well.
"A lot of the talk has been about our pre-season and the results but we just wanted to try to get right for these games."
Lennon went on to speak of his pride at taking Celtic to play a Champions League tie in his home country of Northern Ireland.
"It meant a lot to me personally, bringing a team back home," he added.
"It was a special occasion and I wanted it to be right. I couldn't have asked for any more of the occasion. Both sets of supporters were brilliant."
The second leg takes place at Celtic Park next Tuesday.
