Connor Goldson's double earned Rangers a 2-0 win at Old Firm rivals Celtic to open up a four-point lead at the top of the Scottish Premiership.
Played behind closed doors due to coronavirus restrictions and thus stripped of noise, colour and bitterness, the fixture was laid bare as a football contest and Steven Gerrard's side came out on top.

It was a first defeat in nine games in all competitions for Neil Lennon's second-placed hosts, although they have a game in hand over Rangers with a long title fight still to come.

Quick-fire goals from Ronan Hughes and Marios Ogkmpoe brought Hamilton back into the contest before half-time.
Veteran midfielder Conway then scored either side of Hughes' second goal of the afternoon in the second period to help propel Saints to ninth and leave the hosts to take their place at the foot of the division.
Kilmarnock remain fifth after coming from behind to defeat Livingston 3-1 in their first league match since the entire squad was forced to self-isolate due to a Covid-19 outbreak.
