With Rangers' lead over Celtic in the Clydesdale Bank Premier League stretched into double figures, and Raith Rovers lying in wait should they overcome Dundee United in the Scottish Cup quarter-finals, a domestic clean sweep is very much on the cards.

But, despite enjoying cup final appearances as a coach and manager stretching over 30 years, Smith insists there is no danger of him becoming blase about the occasions.

The Rangers manager will take the Hampden clash on its own merits and enjoy it without looking ahead to the bigger picture in May.

"When someone says you are going to go for trebles, there is an amount of arrogance in that statement," Smith said.

"There is an expectation that we get to these cup finals and are attempting to win these trophies.

"That's what I stress it is, it's an attempt to win.

"For me, it's not the first leg of a treble, it's a cup final.

"If we do win it, we'll be delighted for that reason and that reason alone."

The 62-year-old added: "You always feel very fortunate going into cup finals.

"I've been lucky enough over my time to be involved in quite a number of them both at Dundee United and Rangers, and you still get the same feeling.

"It doesn't matter how often you go, you still get that great desire to win."

There is more than fortune behind Smith's record in guiding Rangers to six cup finals in a two-year period.

"Our squad have shown that, since we came back, they have featured in every cup final in the last three years and that's a big thing," he said.

"We've shown a desire to do well in each of them. We lost out to Celtic in the League Cup last year, hopefully we can make up for that on Sunday."

Smith is tomorrow seeking his 18th trophy in two spells as Rangers manager, a record that this week prompted Ibrox great Willie Henderson to call for a statue to be built to mark his status as one of the club's top bosses.

But, with Smith refusing to look even towards the end of this season, he is not ready to sit down and reflect on his career as a whole.

"It's always nice when someone who has been involved at the club for a long time says things like that," the former Scotland manager said.

"You don't set out for that. When you start as manager, or assistant manager as I did with Graeme Souness, then the strain that runs through Rangers Football Club is that you have to win.

"I've been fortunate enough to have been involved with some terrific players here and they have helped every bit as much as I have helped them.

"No manager gets through without having a good level of player and we've had that here.

"It's nice that people say those things but, like someone asks me if I'm going for a treble, it's another trophy in isolation.

"That may be slightly boring but I always try to take these things as they come."
