Sergio Aguero, Vincent Kompany and Fernandinho scored as Manchester City crushed Chelsea 3-0 on Sunday to establish a five-point advantage over the champions in the fledgling Premier League table.

After going close several times, Aguero celebrated his return to the starting XI by wriggling through Chelsea’s defence to score a 31st-minute opener before Kompany and Fernandinho made the game safe late on. 

The well-earned victory continued City’s impressive start to the season following their 3-0 win at West Bromwich Albion and gave Manuel Pellegrini a first win over his nemesis Jose Mourinho since the Portuguese returned to Chelsea in 2013.

Defeat completed a miserable week for Mourinho, widely criticised for demoting his medics Eva Carneiro and Jon Fearn after last weekend’s 2-2 draw with Swansea City, and means Chelsea have failed to win one of their first two league games for the first time since 1998.

It was also a day to forget for visiting captain John Terry, who watched the second half from the bench after being substituted at half-time — the first time Mourinho had taken him off in 177 league games.

After a flurry of near-misses, Aguero broke the deadlock by exchanging passes with Yaya Toure, darting into the box and placing a low shot beyond the reach of Asmir Begovic, deputising for the suspended Thibaut Courtois.

Hazard forced Joe Hart into a save in the second half, but City looked more likely to add to their lead and so it proved as Kompany headed home from David Silva’s 79th-minute corner before Fernandinho drilled home from the edge of the box.
