Ross County manager Jim McIntyre: “The rivalry is crucial. We want both teams in the Premiership, we want the derby every season as they are great games to look forward to.
“Hopefully we will pick up the points on Friday night but Inverness then go on and get the ones they require too.
“Our aim is to be the best of the rest and pick up as many points as we can. It’s important we just play the game and not worry about what stage of the season it’s at.
“We’ve got to make sure we focus on doing what we do well. If we can get our tactics spot on then we’ve got a chance of beating any team.”
Inverness Caledonian Thistle manager Richie Foran: “At the moment, Ross County are out of the relegation battle in terms of finishing bottom because they have an eight-point advantage over us, but by the end of the game, they might be right back in it and we’ve got to make sure that happens.
“Jim McIntyre has done a fantastic job over there.
“They are a real attacking threat. They have a lot of players who can score goals. They are a dangerous outfit going forward, as are we.
“It will be a big night for both teams. We need to take the ball under pressure and we have players to do that, like Iain Vigurs and Greg Tansey and Iain Polworth.”
