Phil Foden's superb solo goal helped Manchester City see off Newcastle and ensured the defending champions kept up the pressure on Premier League leaders Arsenal.
Foden struck after 15 minutes, gliding in from the right and holding off two challenges before seeing his shot deflected home off Sven Botman.
Newcastle responded well and were causing plenty of problems until City substitute Bernardo Silva slotted home to put the game out of their reach midway through the second half.
The win means City move to within two points of the Gunners, who play Bournemouth later on Saturday, while Newcastle remain fifth, four points behind Tottenham.
