Kenny Miller insists that Rangers have disproved suggestions that there is a huge gulf between the Ibrox side and Scottish champions Celtic.
Celtic eased to a 2-0 Scottish League Cup semi-final win over their city rivals, but Miller took heart from the Ibrox side's second-half display.
"I think the gulf is smaller than people were making it out to be," he said. "It's as simple as that.
"Looking at the second, I don't think there is a lot between the teams."
Leigh Griffiths headed the Scottish champions ahead after 10 minutes and Rangers never looked like staging a comeback after Kris Commons added a second before half-time.
The Scottish Championship side failed to register a single shot on target as goalkeeper Craig Gordon enjoyed a stress-free afternoon.
But, while admitting it was a disappointing first-half display, Miller was critical of people like former Celtic striker Chris Sutton who suggested before the game that the Ibrox side faced being humiliated.
"We saw some stupid comments from ex-players in the press that were wide of the mark," said the former Scotland striker who also previously had a spell with Celtic.
"People were coming along and saying Celtic were going to score this many and that many because they were overwhelming favourites.
"They were overwhelming favourites because they are top of the SPFL and we are second in the Championship.
"That is just the obvious reason why they are favourites. They have got better players because they are playing at that better level.
"They are playing better opposition every week and that makes them a better team, so I don't think the gulf is as big as everybody made it out to be."
