Manchester City cruised into the FA Cup fourth round with a routine 4-0 victory over Chelsea at Etihad Stadium.

Riyad Mahrez set them on their way with a brilliant 23rd-minute free-kick before World Cup winner Julian Alvarez scored a second from the spot seven minutes later following Kai Havertz’s handball.

Phil Foden scored City’s third after 38 minutes, turning in Kyle Walker’s cross.
