All eyes were on Raheem Sterling as Manchester City travelled to the Hawthorns but it was the familiar talent of Yaya Toure that inspired the away side to a dominate victory.
The Ivorian's shot after just nine minutes got Manuel Pellegrini's side off to a roaring start as it glanced off David Silva and trundled past Boaz Myhill.
Fifteen minutes later and the 32-year-old had grabbed his second, nonchalantly curling a shot into the top corner to extend City's lead.
Skipper, Vincent Kompany put the game out of the Baggies reach and headed in from a corner as City delivered an early statement of Premier League title intent.
Debutant Raheem Sterling missed the chance to score on his debut after breaking clear on goal only to see his shot saved by Myhill.
West Brom's only real chance fell to James Morrison who headed straight at Joe Hart from a Chris Brunt cross. Silva and Toure were too much for the Baggies to handle and Man City were by far the Premier League's stand-out performers as they battle to get their crown back. WBA boss, Tony Pulis later admitted he got his tactics wrong by playing with two strikers.
