Rangers boss Ally McCoist has dampened down expectations on Scottish Cup success this season despite his charges emphatic 4-0 victory over Dunfermline at Ibrox.
In the build up to the tie with their League One counterparts, McCoist suggested Rangers could hold their own with the top sides in Scotland.
But after guiding a team to the last eight of a major domestic competition for the first time, McCoist reckons Rangers will have to replicate their performance against the Pars to progress to a semi-final at Ibrox.
McCoist said: "I would be happy if we could replicate that type of performance in the next round against anybody. I thought for the majority of the game we were really good tonight.
"I have no preference for the draw for the next round other than a home tie.
"Can we beat anyone left in this competition? I don't know, I really don't know. That level of performance I would be happy with playing anyone.
"I'm not going to say we would beat anybody because one or two teams - and obviously Celtic - would be favourites.
"There are a lot of good teams left in the competition but if we put in a performance like that then I would be happy to take my chances against most teams - but that is not to say we would win."
Dunfermline counterpart Jim Jefferies reckons his team lacked their usual fighting spirit as they lost 4-0 to their opponents for a second-successive occasion this season.
Jefferies said: "The last two times we played them, Rangers were complaining about us being physical. But we never laid a finger on them tonight.
"If they didn't like what we gave them last time, we should have given them more of it and then we might have had a better chance.
"When you don't compete against a side like that it makes it very tough."
