When it comes to footballing rivalries, it doesn't get much tastier than the encounter between Scotland's big two.
Times have changed over the last few years, as Rangers look to recover from being banished to the fourth tier, and Celtic have had an easy run at the domestic league in their absence. But this season has seen the gap close to its smallest yet and the blue half of Glasgow know that a win on Sunday will reduce the deficit to three points, although the leaders will still have a game in hand.
