Kenny Miller in defiant Rangers title claim as he questions Celtic credentials 'when the pressure is there'

Kenny Miller has claimed Celtic could collapse in the title race if Rangers can land a blow at Parkhead.

Ange Postecoglou's side look to be well on course to claim the Scottish Premiership title as they prepare to face their Glasgow rivals on Sunday.

They lead by six points with just four games left to play, and have a far superior goal difference when compared to Gio van Bronckhorst's men.

That has saw some fans call for the focus to be put on the Europa League campaign and the second leg against RB Leipzig just four days after the derby showdown.

However, defiant Miller insists it's far from over.

The former Rangers and Celtic striker reckons a slip-up at Celtic Park could see the tide turn against Postecoglou's side.

When asked if he would rest players with European football in mind, Miller told Clyde 1 Superscoreboard: "No, no, because it's not over.

"You know it's highly improbably, but it's not impossible.

"If Rangers get the win on Sunday, it's three points. The next three games, who knows what will happen. When the pressure is there to get over the finishing line it's very, very tough.
