Rangers manager Ally McCoist has no fears about his side underestimating Arbroath in Sunday's William Hill Scottish Cup tie after experiencing one cup shock already this season.
The Scottish champions were sent crashing out of the Scottish Communities League Cup by Irn-Bru First Division side Falkirk earlier in the campaign, ending their hopes of retaining the silverware at the first hurdle.
Now, as they prepare to face Second Division opposition this weekend, McCoist said: "We are travelling up to an environment that a lot of our players won't be used to. But I only need to mention Falkirk to them and that should be a warning enough."
He added: "It's a game that we must go and win. The bottom line is when you are playing one of the so-called smaller teams in the cup, your attitude has to be right to play.
"That's the most important thing. If our attitude is right to play then we will have a better chance than not of winning the game. If it's not, then anything can happen. It's all about our attitude and the way we approach the game.
"It's our job, and the players' job, to make sure they are 100% focused - and they will be."
Looking ahead to the visit to Gayfield, McCoist added: "I've played there before and it's certainly an occasion you will remember.
"I will always remember it for being a fantastic playing surface as well and hopefully that hasn't changed. It's also a very welcoming place and the people are great up there. It's what the cup is all about.
"It might be the one of the biggest games for some of the Arbroath players and that can be really dangerous.
"When you are up against an opponent that doesn't have any fear, anything can happen. This tie certainly epitomises what the cup is all about."
