Celtic manager Neil Lennon believes being cup holders will ensure his players won’t underestimate Peterhead.
The Hoops beat Motherwell 3-0 in last year’s final and Lennon feels his squad’s desire to hang on to the trophy will mean they will be professional at Balmoor.
"It's just part of the domestic scene, sometimes it's nice to have the change from the rigours of the championship," Lennon said.
"We're the holders of this competition and we dearly want to win it again.
"The lads got a taste of winning something, for the majority for the first time, so that gives them a big incentive to win it again."
Having been involved in the club’s defeats to Clyde and Ross County, Lennon is all too aware of Scottish Cup shocks.
"There should be a gulf in quality but anything can happen on any given day," he said.
"We have to be ready for that. It's not as if we can just turn up and play 90 minutes and go home. We have to earn the right to play and win the game.
"This will be a huge game in Peterhead's history. These players will be motivated to take our scalp and we have to be very careful."
