After defeating Elfsborg and keeping a clean sheet at Celtic Park, Lennon is confident in his side's ability to secure a result in Sweden
The Bhoys triumphed over the Swedish outfit by a score of 1-0 at Celtic Park thanks to a Kris Commons goal and Lennon acknowledged that it was important to keep a clean sheet at home heading into the second leg.
"I am delighted with the performance and the result," Lennon told reporters after the game. "They made it difficult for us to break them down, but it was not frustrating, it was understandable."
Lennon is aware that his side have more to do in order to secure qualification to the group stages of Europe's premier competition but said that they took confidence from the result.
"We still have a lot to do in the tie but we are confident," he added. "The crucial thing is the clean sheet. That is important. If we score over there Elfsborg have got to get three. The tie is probably in the balance, but we are confident that we can go there and get a result.
"The astroturf might change things with the way I pick my team. But I was pleased with result; I would have taken 1-0 before the game."
Celtic will contest the second leg against Elfsborg at the Boras Arena on Wednesday, August 7.
