And that was how Eden Hazard was missing all through the game... Revenge is a dish best served cold.

Manchester City exacted their revenge on a Chelsea side that has beaten them twice in the Premier League this season with a convincing win that puts them in the quarter-finals of the FA Cup.

tevan Jovetic and Samir Nasri scored the goals that keeps City's dreams of a quadruple alive and the winning margin might have been even more emphatic on a miserable night for Jose Mourinho's men.

If Mourinho's previous visit to Etihad Stadium - a 1-0 victory at the start of February - was a tactical triumph for the Blues boss, then this was something similar for his City counterpart Manuel Pellegrini, who enjoyed only his second success in 10 managerial meetings between the pair.

n truth, the result was rarely in doubt as soon as Jovetic gave City the lead with a fine low finish in the 16th minute.

Chelsea managed just three efforts at goal in the 90 minutes: hopeful shots from distance from Willian and Cesar Azpilicueta that were well off target, and a late Gary Cahill header which was blocked.

With the in-form Eden Hazard shackled by James Milner and Pablo Zabaleta, the Premier League leaders looked short of ideas and City's defensive diligence meant Chelsea never got the chance to break forward in the manner that had proved so decisive in their last meeting.
