Rangers boss Ally McCoist insists there's no favourite going into today's Scottish Cup tie with Celtic.

There remains little to choose between the teams and McCoist believes the tie is as balanced and unpredictable as ever.

"There is very seldom a favourite going into an Old Firm game," McCoist said. "The form book gets thrown out the window, that's certainly the case in the vast majority of them, if not all.

"Celtic have been on a good run. We've done okay, we lost to Hearts obviously and we're not firing on all cylinders as we have been doing.

"But we're confident we can win the game. There is no doubt about that. The personnel we put on the park, we are extremely confident and hopeful we can win the game."

McCoist added: "I don't care who the favourites are. If you look back over time some people's favourites have probably lost the game the majority of the time, that's how crazy the fixture is.

"I have no idea who the favourites are, we don't look at ourselves as favourites or underdogs, we just look upon it as a game we have to win."
