Manchester City’s defensive frailties were exposed today after Pablo Zabaleta was guilty of poor marking for all three of Cardiff City’s goals in a shock defeat for the Premier League title chasers.

With Vincent Kompany and Mateja Nastasic injured in central defense, Manchester City manager Manuel Pellegrini may want to address the lack of quality in depth by picking up defensive cover in the transfer window.

Cardiff City were clinical in front of goal, and took advantage of their chances to score a fantastic shock victory in their first Premier League home match and first Premier League victory.

Here are all of the goals:

Edin Dzeko Goal

Aron Gunnarsson Goal

Fraizer Campbell, 1st Goal

Cardiff Fans Do the Poznan

Fraizer Campbell Second Goal

Alvaro Negredo Goal
