Chelsea 5-0 Man City
Chelsea kept their Champions League dream alive as Manchester City were brushed aside at Stamford Bridge.
Two goals in the space of five first-half minutes from Jimmy Floyd Hasselbaink and John Terry broke City's resistance before Mario Stanic, Frank Lampard and William Gallas extended the margin in the second half.
The comfortable victory was just the tonic Claudio Ranieri needed after an inconsistent spell of Premiership form.
And with three points assured inside an hour, Ranieri was able to rest some of his players ahead of Tuesday's FA Cup quarter-final replay against Arsenal.
Chelsea dominated from the start but struggled to break down a stubborn City resistance.
Peter Schmeichel escaped an early spillage from Frank Lampard's shot and was then alert enough to race out of his box to hack clear of Eidur Gudjohnsen.
And the veteran keeper was at his agile best to pluck Gudjohnsen's shot on the turn out of the air after Hasselbaink set him up.
City's forward threats were rare, though Robbie Fowler did flash a volley across the face of goal midway through the first half.
38 mins: Hasselbaink volleys in Zola's pass
43 mins: Terry heads home Le Saux corner
58 mins: Stanic volleys home after Terry flick-on
67 mins: Sub Cole sets up Lampard for fourth
79 mins: Gallas completes the rout
But it was no more than Chelsea deserved when Hasselbaink broke the deadlock on 38 minutes.
Gianfranco Zola produced some dazzling play to float a ball to the far post where Hasselbaink gratefully volleyed home.
Five minutes later, Schmeichel pushed away a curling Zola shot but was powerless to keep out the resulting corner, Terry heading home unmarked from Graeme Le Saux's flag kick.
Fowler's miserable afternoon was brought to a premature end when he was substituted at half-time, but Kevin Keegan must have wished City's best chance of the match had fallen to the former Liverpool striker and not Niclas Jensen.
Jensen looked certain to pull a goal back when he was sent clear of the defence with just Carlo Cudicini to beat, but the Dane somehow managed to miss by 10 yards from only eight yards out.
The miss was swiftly punished as Chelsea went 3-0 up on 58 minutes, Stanic volleying home after Terry had flicked on another clinical corner.
That gave Ranieri the chance to rest Hasselbaink ahead of the cup clash with Arsenal, but there was no let-up for City.
Hasselbaink's replacement Carlton Cole teed the impressive Lampard up for the fourth on 67 minutes, perfect timing for the midfielder on the eve of Sven-Goran Eriksson announcing his latest England squad.
The only surprise was that lively strikers Gudjohnsen and Zola had failed to get on the scoresheet and it was left to defender Gallas to have the last word.
The Frenchman beat Schmeichel to the ball and got just enough purchase to poke home the fifth and complete a miserable afternoon for Keegan's punchless side.
