A curled beauty from David Silva in a thriller against West Ham in 2013.
City tore through the middle of the Hammers' defence for their opener, with Alvaro Negredo leaving Fernandinho's pass for Aguero to calmly slot home.
Aguero made it 2-0 with a header from David Silva's free-kick but Vaz Te replied with an acrobatic strike.
That set up a tense finish, until Silva found the top corner to seal City's first away league win of the season.
They began strongly in east London, establishing a platform in midfield and controlling that area of the pitch.
West Ham were chasing shadows and City's slick movement and passing saw them take an early lead through Aguero, who galloped clear unopposed after 16 minutes.
