Rodri scored a stoppage-time winner as Manchester City beat 10-man Arsenal to move 11 points clear at the top of the Premier League with an 11th successive victory.
That advantage will be cut to some extent on Sunday when second-placed Chelsea host third-placed Liverpool, although no team has failed to win the Premier League title when beginning the new year with a lead as big as City's.
Arsenal looked to have held out for a draw but Rodri steered in a loose ball in the 93rd-minute to help City maintain their dominant form.
The hosts were the better side early on and Bukayo Saka swept in a deserved opener to finish off a slick move at Emirates Stadium, before the Gunners self-destructed after the break.
