The Scottish Premiership's big two face off for the first time this season but neither go into it firing on all cylinders. Rangers kicked off their campaign with a defeat at Kilmarnock and while they've won both of their league games.
Celtic started with a victory over Ross County, then beat Aberdeen, but were suffered the same fate as their rivals in Ayrshire on Viaplay Cup duty before being held at home by St Johnstone last week.
