Luiz Felipe Scolari's men handed out a 4-0 battering to Harry Redknapp's shell-shocked men at Fratton Park.

That meant the Blues have conceded 10 unanswered goals in 78 and-a-half hours after being hit for six at Manchester City on Sunday.

It was embarrassingly one sided as the Londoners progressed at a canter.

Controversy surrounded the opener as Frank Lampard converted a 36th minute penalty after Michael Ballack went down under the attention of Nadir Belhadj.

Pompey contended the German had dived, but that did little to bother Redknapp's nephew as he sent James the wrong way.

That moment was where the arguing finished for the home side as Chelsea grabbed a second on the stroke of half-time through Florent Malouda and then dominatd the game after the break.

Lampard grabbed the visitor's third three minutes after the restart after David James had failed to deal with a Kalou cross.

Then Kalou got on the scoresheet himself as he was given the freedom of the penalty area to get the fourth after 64 minutes.

It was as poor as it could get for Pompey, who have a lot to do to pick themselves up for a big week starting against Spurs on Sunday.
