Never before have Celtic and Auchinleck Talbot crossed paths in a competitive match.
On Sunday, they meet in the Scottish Cup fourth round, with non league Auchinleck hoping to cause an almighty shock.
Recent upsets across Europe might give the part-time players and long-serving manager Tommy Sloan some inspiration.
Macclesfield FC beat FA Cup holders Crystal Palace last weekend and second division Spanish side Albacete took down Real Madrid in the Copa Del Rey earlier this week.
"I've actually taken in a couple of Celtic games just to help us along, to see the quality they've got," said Sloan, who has won the Scottish Junior Cup six times with Auchinleck.
"What I'm looking for is to be competitive. We don't want it to be a big disappointment at the end of the day and if we can be competitive for most of the match, I'll be delighted with that."
Sundays' match will be Martin O'Neill's first Scottish Cup fixture since lifting the trophy with Celtic in 2005.
"I'm of an age where I remember Martin O'Neill as a player, Nottingham Forrest and what not, he was one of the guys that was always on the TV, what a good player he was," added Sloan.
"It's amazing we're up against him, he's come back in and got them winning again, steadied the ship, and that says everything about him as a manager."
Celtic visit Bologna in the Europa League next week before a trip to Scottish Premiership leaders Hearts but Sloan reckons the visitors will field "a strong side" at Rugby Park.
He said: "Will there be a few changes in the side? I think they're might be, but we'll see on the day. He's not really one for that, Martin O'Neill, making a lot of changes but I think with the week they've got in front of them they're might be two or three changes in their normal side."
