Chelsea are finding it hard to mount a title defense in the EPL this season, drawing the league opener against Swansea, they followed it with a loss away at the Etihad.
With a shaky midfield and unstable defense, a classy City made light work of last season’s champions, as Aguero and co mounted a credible title challenge.
Aguero proved to be the danger man from the start and his hard work paid off in 31st minute, when good footwork saw him clinch his first of the season.
Chelsea tried to fight back, but failed to hit a shot on target for most of the proceeding.
The second half was no different from the first and any hope of fighting back was dashed on the 79th mark when Kompany headed in a corner.
The game was lost for Chelsea, but City was not done as Fernandinho fired from range to complete the rout on the 85th minute mark.
