Callum McGregor has fired a Celtic attacking warning at Rangers as the champions look to put down an early season marker in the race for the title this season.
Ange Postecoglou and his troops welcome the Light Blues to Parkhead tomorrow lunchtime as the Glasgow rivals do battle in the first Old Firm showdown of the season. The Hoops are sitting top of the table ahead of the game with a 100 per cent record after five games and have netted a stunning 21 league goals.
Giovanni van Bronckhorst's men sit two points back with four wins and a draw from their opening five games and have the incentive of knowing victory would take them top of the league standings. That same bonus is on offer to Celtic but the difference being they would increase their advantage to five points in an early season boost. McGregor and his team-mates know what is on the line at Celtic Park and says they are going out to attack their opponents as they bid to make it six wins on the bounce.
