Pep Guardiola’s first taste of the FA Cup ended triumphantly as his Manchester City side thrashed Premier League rivals West Ham in the third round.
City led 3-0 at the break, Yaya Toure starting the rout by firing a debatable penalty into the bottom left corner.
Havard Nordtveit bundled Bacary Sagna’s teasing cross into his own net, just 146 seconds before David Silva’s composed tap-in.
Shortly after the restart, Sergio Aguero cheekily diverted in Toure’s shot to become the third-highest goalscorer in City’s history.
And John Stones headed in his first Blues goal as the visitors comfortably saw the game out in a rapidly emptying London Stadium.
