The Hoops travelled to Italy with hope in their heart after a devastating 3-0 first leg defeat in Glasgow but are odds-on to exit the competition.
The Parkhead boss is desperate for his side to win the game but knows that the margin required to take them through into the next round is probably asking too much from his players.
"It would be a tall order to win the tie 4-0 or 4-1 but we are capable of winning the game and that's what we would like to do," said Lennon.
"If we win it would equal the club record (of wins in Europe in a season).
"Juventus are top of the league again and the draw could have been kinder to us but we want to close the gap on the scoreline and we will have to play at our optimum level to do that.
"It is a fantastic game to play in. We may not be here again as a group, you are playing the champions of Italy who are a very good team so enjoy it.
"Enjoy the stadium, enjoy the atmosphere, don't be intimidated.
"Go and play, the pressure is really off so try to restore some respectability in the tie, play your football and win the game.
"So we have a lot to play for, there is a lot of incentives, however, to qualify would take a minor miracle."
