The Bhoys boss believes that has side are underestimated after their Champions League victory over Spartak Moscow, but warns that the group is still very much an open affair
The Hoops claimed a crucial victory when Greece international Giorgos Samaras headed home a late goal to give his team a 3-2 lead.
"I think people underestimate Celtic," said Lennon after the game. "I don't think we get the respect we deserve but maybe last night's performance might change a few attitudes."
He continued: "We just have to play Barcelona home and away... But it was a huge step for the club. It was our first away win in the Champions League so we have broken a record."
Nevertheless, the Celtic boss warned that there was still 'a lot of football to be played'. The SPL champions currently sit in second position, behind Barcelona, in Group G of the competition, but Lennon insisted that it was still 'an open group'.
He said: "We have two home games and Benfica and Barcelona away so it is still an open group for second place as far as I am concerned.
"It is fantastic but there is a lot of football to be played in the group," concluded Lennon.
