Celtic and Rangers tend to play each other four times every season in the Scottish Premiership and that means multiple opportunities to bet on an Old Firm encounter. In the days leading up to an Old Firm match, you will find each bookmaker starts pricing up the game, starting with winner odds and then adding further markets relating to goals, score and players. It’s not uncommon to see up to 200 pre-match betting markets for a match between Celtic and Rangers considering it’s nearly-always televised, while you can get a similar amount when the game goes In-Play.
