Sergio Aguero struck twice in two minutes as Manchester City came from behind to overpower Burnley 4-1 in the FA Cup third round.
Leroy Sane and Bernardo Silva also got on the scoresheet as City responded impressively to the shock of conceding a half-time lead to Ashley Barnes' superb opener at the Etihad Stadium.
The comeback, which will only increase talk of a City quadruple bid, was inspired by Ilkay Gundogan, the German setting up Aguero for both his game-changing goals in the 56th and 58th minutes.
Peterborough pulled off a stunning FA Cup upset as three goals in the final 15 minutes earned them a 3-1 win against Aston Villa at Villa Park.
