Inverness manager Terry Butcher: "We will give them respect and they deserve that.
"They are a fantastic club. They have come a long way in a short space of time, very much like ourselves, and they have been a credit to themselves in the SPL.
"But having said that, in the two matches against them we have scored three goals in each and we aim to score and win again.
"So everyone is looking forward to it. There have been two crackers and this is the third instalment. There has to be a winner and there has to be a loser so it has the making of another entertaining match.
"There have been so many twists and turns in the previous two matches I'm sure there is going to be more in the third."
Ross County manager Derek Adams: "We have to do a lot better than we did against Motherwell to get through the cup match," he said.
"If we defend like that and don't take the chances we had we will be out of the cup.
"And with Inverness coming off an extremely good result we are going to find it extremely difficult.
"So the players will have to get themselves sorted out and get ready for Tuesday night because we need one big performance to get through to the next round of the Scottish Cup."
