Anthony Stokes has insisted Celtic will give Inverness total respect on Sunday as they look to avoid a Scottish Cup upset.
The Hoops battled their way into the last eight with a replay win at home against Old Firm rivals Rangers and are now hot favourites to go on and lift the trophy.
However, Stokes is taking nothing for granted and is wary of the threat presented by an Inverness side who knocked Celtic out of the competition in both 2000 and 2003.
"After beating Rangers in this competition, everyone more or less thinks it is over but it is never going to be that easy," said the striker.
"We have to give Inverness the same respect that we gave to Rangers in the last round. We have to be focused and go up there to try and get a result."
Johan Mjallby was one of several Hoops players rested when Martin O'Neill's Celtic side lost 1-0 in the cup at Inverness in 2003.
Celtic's assistant manager remembers the night well - and is looking to avoid a repeat.
"We played in Europe against Liverpool before that game and then flew to Inverness," the Swede recalled.
"I was rested for the game and I wasn't too happy and was even more unhappy after the result.
"We were expected to win the game and Martin wasn't too happy when we lost.
"But that happens now and then. We know it's going to be a difficult game.
"You don't expect anything else in the quarter-finals of the Scottish Cup.
"Inverness are flying high after beating Motherwell last week and they started the season ever so well before they had a wee blip.
"They are a side who work very hard and they will be difficult to beat."
