The 25-year-old has been exceptional for the Scottish Premiership side.
Celtic's Leigh Griffiths
The Hoops last reached the group-stages of the competition in the 2013-14 season, but because they failed to progress out of the group, and Griffiths only joined the club in January of that campaign, he did not get to feature in the competition.
And with the Bhoys falling in the preliminary rounds in the two seasons since, Griffiths conceded that he is yet to fully prove himself as the only way that he can completely convince everyone of his talent is by playing amongst the heavyweights in the competition.
"I feel like I am a jinx. Celtic were in the Champions League before I signed," he told the Express.
"The only way I can prove myself to everybody around the world is if we get to the Champions League and I play when we get there.
"That is the way I am judged, by scoring goals. Gary Hooper did it when he was here, and hopefully that is how I will fondly be remembered – as one of the great players to score in the Champions League."
While Griffiths currently feels like a jinx, he will undoubtedly know that he has an excellent chance to put the past pain behind him this season.
Brendan Rodgers' men face Hapoel Be'er Sheva in the first-leg of their play-off tie on Wednesday knowing that a win against the Israeli side over the two games will see them end their long wait to reach the group-stages.
And with Griffiths showing in the previous rounds that he has not lost his goalscoring touch from last season - he has scored in three of their four preliminary fixtures so far - he will be looking to play a key part in ending their hoodoo by bagging the goals that take them to the stage that has eluded them over the past few years.
