A Yaya Toure double and Vincent Kompany's first goal in over a year helped their side overcome a plucky West Brom side at the Hawthorns and top the Premier League after the first round of games.
The Ivorian and Belgian internationals were much maligned last season after dropping from their previously high standards which saw both considered the best in the league for their respective positions. Their emphatic performances will halt suggestions the veterans are past their peak; it also could not have come at a better time as they play title rivals and reigning champions Chelsea at the Etihad on Sunday,
With the Albion welcoming new £12 million signing Salomon Rondon to the crowd, they would have wanted to impress and showed they are a step up from previous club, Zenit St Petersburg. However, his new teammates got off to a horrible start when Toure scored in the 9th-minute. There was some confusion over who scored as the midfielder's shot deflected off David Silva after Jesus Navas picked out Toure outside the box.
City had won their four previous opening week games and that look almost certain to extend to five when Toure grabbed his second of the game on the 24th-minute as he slammed the ball from the edge of the penalty box after a clever one-two with international and club teammate Wilfried Bony. Incidentally, the goal was the tenth goal out of 30 overall to be scored by an African this week - it took 120 goals overall for that figure to be reached.
Such abandon of defence almost lead to City putting the game beyond doubt as Raheem Sterling, the most expensive English player in history missed a guilt edged chance towards the end of the first-half. Finishing, one aspect of his game criticised when at Liverpool, clearly still a problem for the 20-year-old.
It would have been a bigger problem if Saido Berahino's goal moments afterwards was allowed to stand. Unfortunately, it was correctly ruled offside.
This game is now the fifth time in-a-row the Midlands outfit had conceded three against City and the second time in succession they have been goalless. Clearly Pellegrini's men are a problem for the Albion but they will not face opposition with this calibre every week and they showed enough to suggest they will not be relegation threatened.
