Assistant manager Paul Sheerin is using his experience of stunning Celtic with Inverness in 2000 as a reminder of a possible cup upset as his Kilmarnock side host Cove Rangers on Saturday.
Immortalised by the famous headline 'Super Caley Go Ballistic Celtic Are Atrocious', Caley Thistle's 3-1 victory is remembered as one the biggest shocks in Scottish Cup history, with Sheerin scoring from the spot to seal victory.
While he insists he won't "bore" his current charges by regaling old stories of a momentous night, the former midfielder warned that League 1 Cove will arrive in Ayrshire with a similar mindset.
“It is nice memories," Sheerin said. "It shows you what can happen and obviously upsets do happen. It was a momentous occasion for the club, they were relatively new to the league and that was part and parcel of the shock as well.
“There was belief because you always have to believe as players I know Paul (Hartley) spoke about not feeling any real pressure which is understandable.
“At that time, Inverness had that mindset that there was no great pressure on us, no one expected us to do anything so that took the edge of it and we tried to enjoy it as much as we could, and obviously the way it worked out was something that nobody really expected.
“Cove will come here determined to be one of the clubs who cause an upset. We have done our work and hopefully that will stand us in good stead and not allow a shock tomorrow. Your attitude and application has to be spot on.
“We know what they will come with, we know shocks can happen but hopefully we will not allow that tomorrow.”
