Blues momentum vital - Ancelotti

Goals from Nicolas Anelka just before half-time and two quickfire strikes after the interval from Michael Ballack and Ashley Cole - his first at Stamford Bridge - completed the demolition job in a stylish, exciting and fluid display.

"We have showed that we can adapt to different systems and shapes with intelligent movement and I am pleased with the way my attacking players have shown they can move into spaces whatever system we play," said Ancelotti. "I am happy because we showed good play on the pitch. We have to maintain this moment."

The defeat would have been much heavier if Burnley goalkeeper Brian Jensen had not pulled off a string of fine saves. The win put Chelsea back on top of the table with four wins out of four. The fluidity of Chelsea's football was unstoppable with players inter-changing roles with ease.

Acelotti added: "We have a possibility to win the league. We have started well but we know the season is very long. I have trust in this squad and all of my players are hungry to show what they can do and to win every game."

Ancelotti stressed the Blues would not be adding to their squad before the end of the transfer window - reiterating yet again they had no interest in Bayern Munich's Franck Ribery.

Meanwhile, Burnley boss Owen Coyle admitted his side had been given a footballing lesson by Chelsea.

Coyle's side, promoted via the play-offs last season, have already beaten Manchester United and Everton so far this term. But they looked positively pedestrian against a Chelsea side that flowed forward effortlessly.

The Scot said: "There might have been a suspicion of offside about their first goal but there is no doubt about it, Chelsea were deserved winners. I have no argument with that.

"We will take our medicine and it was a lesson at times with the way Chelsea passed and moved the ball. But that is why they are world-class players. We will look to pick ourselves up and go again."
