Pep Guardiola's side emerged victorious in this rescheduled Premier League clash, with goals from Rodrigo and Kevin De Bruyne securing the three points.
The teams were meant to face each other ten days earlier and City returned from their winter break with a spring in their step, creating a number of chances in the opening exchanges, but were thwarted by a rigid Hammers defence.
The hosts kept probing and eventually, the deadlock was broken in the 30th minute from a set-piece, as Rodrigo headed expertly beyond Lukasz Fabianski from De Bruyne's curling corner.
On the hour mark, City were celebrating their second as De Bruyne drilled the ball into the net from inside the 18-yard box after neat link-up play with Bernardo Silva.
Guardiola's men professionally saw out the last 25 minutes to claim a well-deserved win!
