West Ham had their moments throughout the 90 minutes, but it came as little surprise when City added a fourth in added-on time as Sane netted his second.
Find out how all of the action unfolded in East London courtesy of Sports Mole's minute-by-minute updates below.
WEST HAM UNITED SUBSTITUTES: Adrian, Cresswell, Ogbonna, Noble, Carroll, Hernandez Lucas Perez
MANCHESTER CITY SUBSTITUTES: Muric, Kompany, Stones, Mahrez, Jesus, Zinchenko, Foden
West Ham sit in 13th position in the table and could move into 12th with a victory. Burnley do not host Newcastle United until Monday, so a draw or defeat would see the Hammers remain where they are.
WEST HAM UNITED XI: Fabianski; Zabaleta, Diop, Balbuena, Masuaku; Diangana, Rice, Obiang; F.Anderson, Antonio, Arnautovic
MANCHESTER CITY XI: Ederson; Walker, Otamendi, Laporte, Delph; Fernandinho, Gundogan; Sterling, D.Silva, Sane; Aguero
