City were at their scintillating best for long periods and West Brom struggled to cope.
Two first-half goals from Sergio Aguero put the game beyond too much doubt. His first was a lethal finish from close range after a wonderful throughball from Ilkay Gundogan; his second a long-range bender that flew into the top corner and gave Ben Foster no chance.
Aguero turned provider late on, setting up Gundogan to score from inside the area, before the German bagged his second with one minute remaining. Gundogan, who was superb throughout, totally deserved his moment in the spotlight.
It was the fourth game in succession City have scored at least three at the Hawthorns and the result sees them move back to the top of the Premier League after temporarily dropping to second following Arsenal’s win away at Sunderland.
