The Celtic boss has said he is looking forward to watching some good, attractive football after drawing the Liga giants, along with Benfica and Spartak Moscow in Group G
The SPL champion has also been drawn alongside Benfica and Spartak Moscow and Lennon hopes that the club's past experiences against all three sides will benefit them.
"We're familiar with all three teams. Under Gordon [Strachan] we played Barcelona and Benfica, and we also knocked out Moscow in a playoff," Lennon told Sky Sports. "Let's take it as it comes and see where we are first and what fixtures we've got coming up. It's fantastic to be here and we're going to enjoy it. I'm delighted to be here and it's fantastic to be involved in the draw.
"It's a tough tough group, all the teams play good football so it should be quite attractive to watch. It's very exciting to be in a group with Barcelona, tough but a real glamour game for the club. The other two are huge clubs in their respective countries."
