He said: "I can talk about my experiences. I definitely think that the Worthington (League) Cup victory when I played at Liverpool was the real catalyst to going on and winning that treble, without a shadow of a doubt.

"It gave the players the belief. Liverpool had gone a similar time without winning something, and the players built on it. Once you've got one it becomes a bit of a habit.

"I think a first trophy would bring back a greater belief, within the club and the fantastic fan base that we've got here – the people that come to Ibrox.

"Getting that first one is crucial. We're in four competitions. This is an early opportunity to try and get to Hampden.

"It's the first of the four competitions that we're in that the final comes upon us so we're just trying to keep the momentum going.

"People might look at it and say it's at the bottom of our priority list but no – I think this club needs to win.

"So we'll be very, very strong and our preparation will be diligent going into this game, just like it's been in this recent run of great results."

Livingston are a familiar foe for Rangers, having visited Ibrox less than two weeks ago when Gers came from behind to win 3-1.

McAllister is wary of the threat posed by Livi and expects another tricky test.

He added: "We've got to be on our toes. It's a difficult opponent, we only played them recently. They're organised, competitive, they'll be physical.

"They get results. It's going to be a tough game."
