Rangers' Clydesdale Bank Premier League title triumph means they qualify automatically, while the Hoops must overcome Portuguese outfit Braga in the third qualifying round to join their Old Firm rivals among Europe's elite.

Miller knows all too well just how tricky qualification can be, after Rangers crashed out to Lithuanian outfit Kaunas within weeks of his arrival for his second spell at Ibrox in 2008.

He said: "We've been in that position, we were in that position the first year I came here and could have had a really tough draw in the qualifiers.

"We were actually quite fortunate but we never performed and let ourselves down that year.

"That's what happens in the qualifiers, there are a lot of good teams in it.

"We are fortunate enough that we are straight in this time and can sit back and relax and look forward to the draw."

Meanwhile, Miller admits the loss of another first-team regular in the shape of Kevin Thomson is a blow but insists there are plenty of candidates to fill the void.

Thomson became the latest player to quit the Scottish champions this summer, when he signed for Middlesbrough in a £2million deal.

He joins former Ibrox team-mate Kris Boyd at the Riverside, just weeks after the striker's own departure from Rangers.

Miller said: "Losing Thommo is a blow. He has been a regular starter for the team over the last two or three years he has been at the club so he will be a loss.

"But you've got to move on. When one door closes, another opens. There are lads who are more than capable of filling his shoes.

"Lee McCulloch, Steven Davis, John Fleck and Maurice Edu can all play in that position. We have more than cover for him. It's an opportunity for somebody else to come in to the team."

As well as Thomson and Boyd, Nacho Novo, DaMarcus Beasley and Steven Smith have also left the Scottish champions since the end of last season.

So far, attempts to add to the squad have failed after Burnley winger Chris Eagles rejected a move to Rangers after failing to agree personal terms.

Miller admits new personnel is vital but was also keen to point out Rangers have been able to cope without an injection of fresh talent for the last two years.

"If we don't sign players, we will have to be good enough," he said.

"But we are looking at hopefully bringing in a few fresh faces. We have lost a lot of players.

"With Thommo gone, that's five important first-team squad players so we are going to have to replace at least a couple of them, I would think.

"But, if nobody comes in, nobody comes in. It's something we have had to deal with for the last couple of years.

"We hadn't brought anybody in but we hadn't really lost any big players, like we have done this summer.

"But if nobody comes in, we will carry on regardless as we have done for the last couple of years and hopefully retain our title."
