Riyad Mahrez and Julian Alvarez scored as Manchester City beat Premier League rivals Chelsea to reach the Carabao Cup fourth round.
Both sides had chances in an open and even first half to the game as Jack Grealish fizzed a shot just wide, while 18-year-old midfielder Lewis Hall was denied by Stefan Ortega for Chelsea.
But Mahrez struck when he drove in a free-kick early in the second half.
Alvarez sealed the win with a close-range finish soon after.
It was a deserved win for Manchester City as the eight-time winners maintained their record of never losing in the third round under Pep Guardiola.
