Rangers run away with the Old Firm derby at Ibrox! Kemar Roofe's brace sandwiched a vicious strike from Alfredo Morelos to put Steven Gerrard's side firmly in control. Odsonne Edouard had equalised in the first half for Celtic, who also had Callum McGregor sent off for two bookings in as many minutes. But it was Rangers' day and they put the icing on the cake in stoppage time, when substitute Jermain Defoe got in on the act. Gerrard's men remain on course to complete the Scottish Premiership season unbeaten, while that is 18 wins from 18 on home soil.
