Chelsea 6 Manchester City 0:Coach Avram Grant's promise of a more attacking Chelsea finally materialised as they sent Manchester City crashing to their biggest defeat of the season with a six-goal super show at Stamford Bridge.

A brace from Didier Drogba, which took his tally to four in the last three games, was supplemented by further goals from Michael Essien, Joe Cole, Salomon Kalou and Andriy Shevchenko as Chelsea ran riot.

It was their biggest win of the campaign — bigger than any they enjoyed under Jose Mourinho — and the manner in which they deconstructed a City team unbeaten in their last six outings was both stylish and impressive.

The win increased Chelsea's unbeaten run to seven games since they lost Grant's first outing in charge at Manchester United last month and it stretched their record to 68 homes matches without defeat in the league.

Chelsea fashioned the opening goal in the 17th minute with a well worked move.

Mikel John Obi found Frank Lampard in space midway in the City half and the England midfielder wasted little time in putting the ball into the path of Essien.

The Ghanaian needed little invitation to run on and unleash an angled drive that eluded City keeper Joe Hart and flashed into the far corner of the net.

But City were still dangerous on the break and when Mikel fouled Elano 25-yards out, Cech was forced into a flying save to keep out a vicious free-kick from Marin Petrov.

Moments later, a header from England international Micah Richards was deflected to safety by Lampard.

But City had Richard Dunne to thank for preventing Drogba from adding a second in the 24th minute when his deftest of touches took Joe Cole's cross away from the former Marseille striker on the six yard box.

In the 26th minute, Salomon Kalou fed Drogba with a cleverly angled pass but the Ivory Coast striker, who has scored two goals in his last two games, sent a poor shot into the side-netting.

But Drogba got it right five minutes later when Lampard split the City defence with an inch-perfect pass to the Ivorian who controlled the ball perfectly before drilling a low shot under Hart for his third goal in as many games.

City should have pulled one back in the 37th minute but, when Michael Johnson's pass found Ireland in space on the edge of the penalty, the City midfielder could not even hit the target.

Chelsea continued to play some sparkling football after the restart. Lampard, who had been in glorious form during the opening period, found Cole on the right flank with a typically accurate 40-yard pass.

It set the midfielder up for a run at the City defence but he elected to pass the ball to the unmarked Kalou on the edge of the penalty area.

Kalou should have hit the target but the ball took an unfortunate bobble at the moment of impact and his shot went high over the crossbar.

But Chelsea were three-up in the 56th minute thanks to Drogba's fourth goal in three games.

The move had been started by a fine run down the left flank by Paulo Ferreira.

His low cross into the penalty area was flicked on by Drogba into the path of Kalou who then fed Lampard on the penalty spot.

The England midfielder's shot was brilliantly saved by Hart but Drogba reacted quicker than the City defence to smash home the loose ball.

Cole made it four in the 59th minute when the England midfielder finished off a three man move that was started in Chelsea's own half by an overhead clearance from Brazilian defender Alex.

Drogba headed the ball into the path of Cole and he left the City defence behind before drilling a low shot into the net.

Chelsea made it five in the 75th minute when Essien's pass caught the City defence square and Kalou took his time before beating Hart with an angled shot into the far corner.

Substitute Andriy Shevchenko completed the scoring in the dying seconds when he shot past Hart from Essien's pass.
