Callum McGregor has challenged his team-mates to "be Celtic" as they prepare for the Glasgow Derby at Ibrox this weekend.
The midfielder believes the key to success is focusing on their own game and style, rather than getting caught up in the occasion.
Speaking to club media, McGregor said: "A unique game, unique circumstances, obviously winner takes all, so you need to do a lot right. It's cup football, regardless of the opponent, you need to turn up and do everything you can to win the game.
"We know that, we know it's played to a finish, and we have to go there and do a lot right; impose our style and tempo on the game, be as aggressive as we can be, and hopefully we'll finish with the result that we want."
He emphasised the importance of not getting "sucked into the game in terms of the occasion and the atmosphere", which he admitted is "easier said than done".
McGregor said that whenever they manage to impose their style, they generally come away with good results and this should be their template for the upcoming game.
Celtic will be travelling to Ibrox without any away support due to the ongoing ticket dispute between the clubs, but McGregor said the players understand exactly what is at stake.

He added: "Obviously, we're disappointed that we don't have any supporters in, but they can rest assured that the players know what the game means; they know what it means to them and to the football club.
"So we go there with everything to try and win the game."
McGregor also revealed that some of Celtic's summer signings have already been seeking advice about what to expect from the fixture, including Mika Baur. He said: "Funnily enough, I've actually just had my conversation with Mika there and he's asked me a little bit about the game.
"So it's probably just try and drip-feed what to expect over the next couple of days, just try and plant it in people's heads and explain to them what the game is about."
The midfielder also praised manager Martin O'Neill for his calming influence and experience in major occasions. McGregor said: "He's a man of huge experience, managed many, many big games.
"He brings that calmness, and generally in the bigger moments, you need to be calm and be less emotional.
"And give the players the confidence to go and carry out the game plan that we want. Generally over the piece, we've done pretty well."
