Maurice Ross insists Rangers are the best team in Scotland as he fired a warning to Celtic that the Ibrox side didn't need to get out of second gear on Saturday.
Steven Gerrard's men won 2-0 in what was arguably their most comfortable victory in an Old Firm in more than a decade.
And the former Rangers defender reckons that it came as no surprise because Celtic are the 'weakest' they've been in more than 20 years.
But Ross reckons Celtic should be worried by the fact Rangers didn't need to be at their free-flowing best to comfortably take all three points.
He told BBC Sportsound: "They are talking about 'Rangers defended their box'. Rangers didn't need to defend their box. For me, the way Celtic played it their understanding of 3-5-2 looks very basic.
"Rangers were in second gear yesterday. If you could super-impose a different coloured strip onto Celtic yesterday, it didn't look like a Rangers v Celtic game, did it?
"I thought Rangers were in full control and I think Rangers right now are by far the best team in Scotland."
With a surprise start in defence for youngster Stephen Welsh and Patryk Klimala starting up front, it wasn't the usual Celtic team fans have become accustomed to.
The likes of Odsonne Edouard, Ryan Christie, Nir Bitton and James Forrest were all missing from the lineup and Ross reckons it's been a long time since they were so poor.
Ross added: "As soon as I saw the teamlines I thought the writing was on the wall for Celtic. I think Celtic have got a good squad but that starting eleven is the weakest I have seen in 20 years."
