The Bhoys had some good chances in the second half with both James Forrest and Charlie Mulgrew coming close but in the end could not deny Cesc Fabregas heading home the winner with just under 15 minutes left.
"We had two fantastic chances, Victor Valdes' save (from Forrest) was amazing and Charlie Mulgrew should score (with a header),” said Lennon.
"It was a great opportunity and then two minutes later Cesc scored the winner so the game hinged on those five minutes.
"We needed our keeper (Fraser Forster) to make great saves at the end but that was almost academic.
"At 11 versus 11 I was really happy, especially in that spell after half-time. You are talking about the best club team in the world and they wear you down."
