London:
Chelsea extended their 100 per cent record under Carlo Ancelotti as goals from Ashley Cole, Michael Ballack and Didier Drogba gave them a comfortable 3-0 victory over London rivals Tottenham at Stamford Bridge on Sunday.
The win was enough to lift them back above Manchester United to the summit of the Premier League, three points ahead of their rivals, who had briefly gone top with a 4-3 win over Manchester City earlier in the day.
Tottenham were second best but left having lost more than three points as defenders Ledley King and Sebastien Bassong both suffered serious-looking injuries.
Drogba, along with Jose Bosingwa, had returned to the home line-up following midweek Champions League suspension, with Branislav Ivanovic and Salomon Kalou making way.
Chelsea almost opened the scoring in the eighth minute when right-back Bosingwa latched on to Ballack's header and fired in a shot from the edge of the area.
Tottenham goalkeeper Carlo Cudicini, the ex-Chelsea man, was relieved to see the ball rebound back into play off top of his near post.
Jermain Defoe should have given Tottenham the lead three minutes later though when he was played through by Wilson Palacios's fine ball.
The England marksman already has five Premier League goals to his name this season but this time was denied by the boot of Petr Cech, the Chelsea goalkeeper.
Cech was needed again to deflect away Tom Huddlestone's long-ranger, which caught him by surprise, and Jermaine Jenas fired wide by the most slender of margins from the next attack.
Chelsea's reply was a header from Frank Lampard that wasn't far away either and an effort from Nicolas Anelka that fizzed into the side-netting.
The home side's appeals for a penalty when Vedran Corluka and Ballack collided in the box were ignored by referee Howard Webb but the reprieve was short-lived for the Croatia defender as Chelsea scored seconds later.
Drogba fired in a cross from the right that was met by Cole's diving header, with the left-back having stolen in ahead of Corluka.
The second half began with Lampard scuffing a good chance wide but there was trouble for Tottenham when centre-back King's already-damaged knee failed him and he was replaced by Alan Hutton.
Webb had another decision to make when Ricardo Carvalho challenged Robbie Keane in the Chelsea box. Again he ruled no penalty should be awarded although the defender appeared to clip Keane.
Chelsea doubled their lead through Ballack straight afterwards. Anelka's cross was chested down by Drogba and Cudicini could not hold on to the low shot that followed. Lampard was first to the loose ball and set up the German for a tap-in.
Further disaster for Corluka and Cudicini followed when Cole's long ball over the top sent Drogba clear of the Croatian, who had switched to centre-back in King's absence.
Out came Cudicini only for Corluka to divert the ball past him and Drogba collect it for another tap-in.
Cudicini almost cost Tottenham another when he let slip a shot from John Obi Mikel, who had come on for Ballack, but the Italian just managed to claw it away before it trundled over the line.
Yet there was further misery for Spurs when Bassong fell heavily and had to be stretchered off, a fate that then befell Drogba five minutes before the end.
