The Hoops have been given little chance of qualification after being drawn against Barcelona, Benfica and Spartak Moscow.
"Barcelona are the best team in the world, but Benfica and Spartak are beatable. At home, even Barcelona are beatable," said the 18-year-old.
"I know people think that's unrealistic, but you never know with Celtic at Parkhead - it's just a different level.
"It's a massive club and we've got a good, young set of players. Hopefully we can take that on to the park and get a few results and qualify for the last 16."
Celtic became the first British club to win the European Cup when they triumphed over Internazionale in 1967.
