McCoist doubtful over cup run
Rangers boss Ally McCoist admits he is not sure if his Ibrox side are good enough to continue their William Hill Scottish Cup march.
The Light Blues booked a quarter-final slot with a much-improved display as they ran Dunfermline ragged in a 4-0 drubbing.
Dean Shiels grabbed a hat-trick as he impressed alongside the scorer of the League One leaders' third strike, David Templeton.
Rangers will rightly fear a tie with bitter rivals Celtic when the draw for the last eight is made on Sunday, but if they can replicate this type of form in the next round, the League One leaders may just handle anything else the Scottish Premiership has to offer.
However, McCoist is not so certain.
The Ibrox manager 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."
Rangers were ahead after eight minutes when Templeton drove into the box before attempting to back-heel into the path of the overlapping Lee Wallace. However, the ball broke off Ryan Williamson's feet and before the midfielder could clear Shiels pounced to roll home from six yards.
He struck again on 24 minutes when he pounced on keeper Ryan Scully's spill from a Jon Daly header before Templeton notched up the third with a tidy finish after driving half the length of the park to score.
And Shiels - who has remained at Ibrox despite rumours linking him with a January move - slotted home his sixth goal in five games just after half-time from another rebound after Scully had rushed from his feet to block at Wallace's feet.
It was a second successive four-goal defeat for Jim Jefferies' side against Rangers and the East End Park boss admitted his side failed to show their usual fighting spirit.
He 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."
