Portsmouth 0-4 Chelsea

A dominant Chelsea side booked their place in the fourth round of the Carling Cup on Wednesday night after cruising to victory at Portsmouth.

Frank Lampard clinically slotted in a penalty to put the Blues ahead after Michael Ballack was brought down by Nadir Belhadj.

Florent Malouda lashed in a shot for Chelsea and Lampard walked in another after David James deflected a Salomon Kalou cross against his knee.

Kalou rifled in a shot to complete the rout over a tame Pompey side.

The Fratton Park club's fans must have been in apprehensive mood for the tie against Chelsea after the 6-0 mauling their side suffered at Manchester City on Sunday.

And their fears were realised as Chelsea eased to victory against the south-coast club who they beat 4-0 on the opening day of the Premier League season.

The visitors had quickly taken a grip of the game against a Pompey side boss Harry Redknapp set up in a defensive 4-5-1.

Chelsea worked a chance for Didier Drogba and he whistled a shot past the post before Lampard played a delightful ball to release Kalou through on goal.

Kalou squeezed his effort just wide as he was closed down by on-rushing keeper James but Pompey could only hold out for 36 minutes.

Nadir Belhadj carelessly brought down Michael Ballack, who was going away from goal, and Lampard clinically slotted in the resultant penalty.

Kalou had a big influence on the game and teed up Malouda to lash in a shot just before half-time to extend Chelsea's lead.

It was all too easy for Chelsea and a Kalou pull-back from the byline resulted in Lampard's second, which was only celebrated after the midfielder apologetically lifted his arm to signal a goal.

Pompey's defence is proving a fragile unit this season and they were agains exposed and Ivory Coast striker Kalou powered in a shot to wrap up a comprehensive win.
