Former Rangers assistant Gary McAllister claims he "cannot see Celtic dropping points" in the title race and feels the league might be a step to far for the Ibrox side this season.
Philippe Clement's men currently sit eight points behind the Scottish games with two games in hand.
And McAllister insists the Light Blues most simply focus on themselves.
"Rangers can't look at Celtic too much," he told BoyleSports who offer the latest SPFL betting odds. "They have to take games as they come and try to win as many of them as possible," he said.
"If Celtic drop points, so be it, but Rangers can't hold their hopes on that. They have to concentrate on winning games.
"It's happened before - plenty of teams have come back from a deficit, but if I'm being truthful, I can't see Celtic dropping points."
The Scotland hero also admitted that Hellas Verona left-back Josh Doig has long been admired at Ibrox since his days at Hibernian.
He added: "Josh Doig has been on Rangers' radar for a while as he was a standout player at Hibernian.
"He's a very modern full-back who's very athletic and loves to bomb forward. He'll gain experience on the defensive side of things as he develops.
"That's his main role, but you can never stop a young player from wanting to gallop forward and join in. It's no surprise to see Rangers after him.
"Borna Barišić has been at the club since 2018, and he's been a fantastic servant for the club. I think Doig would offer some fresh legs and he'd be a good signing for most clubs."
