Victory over Burnley tomorrow would make it a club record 10-match winning streak in all competitions and further evidence was provided in emphatic fashion here at The Hawthorns that they are every inch contenders to retain their crown.
What is most impressive about City right now is that they are sweeping aside all before them without a recognised striker.
Midfielder James Milner again led City’s front-line in the absence of the injured Sergio Aguero and Edin Dzeko, with the fit-again Stevan Jovetic only ready to be named among the substitutes.
It made no difference, however, as Pellegrini’s side raced into a two-goal lead within the opening 13 minutes.
First, Ben Foster had a moment to forget in the eighth minute as he dropped what a appeared a routine Jesus Navus cross — gifting Fernando the simplest of finishes into the empty net.
Then five minutes later, Joleon Lescott — in his first appearance against the side he left for The Hawthorns this summer — mis-timed a challenge on Silva to hand the champions a penalty.
Toure made no mistake with the resulting spot kick and, although Foster guessed the right way, the Ivory Coast midfielder’s shot was precisely dispatched inside the left post to leave the goalkeeper with no chance.
So poor were their opponents, City looked capable of scoring every time they ventured forward and it was no surprise to see them add a third before the interval.
Fernando drove forward unopposed before slipping the ball out wide to Navas, he laid off neatly to Silva, on his inside, and the unmarked Spaniard curled expertly inside the far upright.
Craig Gardner and Saido Berahino quickly spurned openings for Albion, but they did pull one back in scrappy circumstances with three minutes remaining when Joe Hart flapped at a Baggies corner before the ball was inadvertently diverted goalwards by Brown Ideye after a deflection off the back of Bacary Sagna’s head.
It was too little, too late for them, yet the same cannot be said of City and their title hopes as their momentum builds.
