Ross County captain Marcus Fraser insists the Staggies must believe they can take points off the Old Firm.
County face Celtic at Parkhead in the Premiership today, before making the trip to Ibrox to face Rangers on Wednesday.
The Dingwall men have not fared well against the Glasgow clubs this season, shipping 14 goals in the three losses they have suffered against Celtic and Rangers so far.
Defender Fraser knows games against the Old Firm will not determine the Staggies’ campaign, but he is eager give both clubs a tougher test in the coming days.
Former Celtic player Fraser said: “The managers have told us that if we put that much work into a game, we can win any game.
“We are obviously playing the two best teams in the league, but we need to use that as a motivation.
“Although our results against them haven’t been so good against them, we need to try and correct that.
“We are going to Celtic Park and Ibrox back to back which doesn’t often happen.
“These are challenges we just need to stand up to. If we want to push up the league, we need to put in performances against these top teams.
“If we get something from these games, all of a sudden you’re picking up points people didn’t expect you to and you’re looking at the table even more positively.
“If we can get something it’s massive.”
Fraser made his first outing since December 21 when he returned to the right back slot for Wednesday’s 0-0 draw at home to Hearts.
The Staggies have faced criticism for their defensive record this season, with their goals against tally of 42 the worst in the league.
Fraser hopes his side took a step in the right direction by recording a clean sheet against the Jambos, with the 25-year-old adding: “It gets spoken about, but we can’t dwell on it too much. We are working hard on it, but obviously as players we need to do better.
“The managers can set us up but we need to defend better. It showed against Hearts we were doing that.
“It’s massive for defenders to keep clean sheets. We need to get back to doing that.
“If we can keep clean sheets we’ve got the chance of winning any game.
“If we keep the door shut at the back, it gives us a licence for the strikers to get one chance and put it away to get all three points in.”
County have added Coll Donaldson to their backline during the January transfer window, with Fraser pleased with the way the former Caley Thistle player has settled in.
He added: “Coll has been brilliant. He has settled in well, he’s a confident lad.
“He’s out of his shell now which is good. The performance against Hearts showed that, he was defending on the front foot, getting in front of attackers and winning the ball.
“That drives us up the park. Fair play to him, he has come in and done really well.”
