The last time Manchester City went scoreless at the Etihad was in November 2010 against Birmingham City and the last time they lost at the Etihad was in May 2013; both of those have changed after today's match against Chelsea. Jose Mourinho's men put in a truly stellar performance all-around to stun Pellegrini's City.
After the visitors dominated the first half, Ivanovic opened the scoring with a low and hard shot from 20 yards out.
The Serbian right-back smashed home past Joe Hart and into the corner of the net to give Jose Mourinho's side a priceless lead after an impressive spell early on.
As City pushed forward and look to grab an equalizer, Chelsea went springing on the counter as Samuel Eto'o, Nemanja Matic and Gary Cahill all hit the woodwork as Chelsea continued to look the better team.
City had their own chances late on as David Silva and Stevan Jovetic tested Cech, but Chelsea held on for the win to draw level on points with City in second with both trailing Arsenal by two points.
