Rangers defender Darren McGregor has urged the Light Blues to pile some early pressure on rivals Hearts in the Scottish Championship.
Ally McCoist's team moved to the top of the table with Friday's 4-0 win over Raith Rovers, but unbeaten Hearts will regain the lead with a point at Dumbarton.
McGregor is quoted as saying by Sky Sports News: "Hearts have had the best start to the season they could possibly have imagined. They are a young squad but Robbie Neilson has got them playing well.
"It will be interesting to see when the shoe is on the other foot and they are chasing us for a change.
"I'd be surprised if they went the whole season unbeaten, so it will be interesting when they get a defeat to see how they react to that."
Rangers and Hearts faced off back in August, the Edinburgh outfit winning 2-1.
