Terry, Boulahrouz, Ashley Cole, Joe Cole (Wright-Phillips 79),
Essien, Ballack (Lampard 61), Makelele, Robben (Drogba 83),
Kalou.

Two second-half goals were enough to see Chelsea into the fourth
round of the Carling Cup at Blackburn's expense.
Joe Cole celebrated his first start of the season by converting
Salomon Kalou's cross after 53 minutes.
Kalou tapped in the second after Brad Friedel had parried
substitute Shaun Wright-Phillips' shot.
Blackburn had their chances in an entertaining tie, with Shabani
Nonda looking particularly lively, but Chelsea were too
strong.
Rovers boss Mark Hughes, in his 100th game in charge, also saw
Nonda and Morten Gamst Pedersen pick up injuries.
It was Nonda who had the first chance of the game, the striker
bursting through before sending his effort narrowly wide.
But Chelsea got into their stride, with the lively Kalou and Arjen
Robben going close.
Blackburn almost took the lead in the 41st minute when Pedersen
rattled in a free kick from distance but Hilario turned the ball
around the post and it was scoreless at half-time.
Pedersen limped off in the 48th minute and Rovers' plight worsened
five minutes later when Cole put Chelsea ahead - although the hosts
were convinced the England midfielder had handled the ball in the
lead-up to the goal.
Nonda was then stretchered off after a collision with John Terry,
who later had a header scrambled away.
A minute after coming on, Wright-Phillips delivered the killer blow
to Blackburn's hopes of recovery.
Brad Friedel did well to parry the winger's fierce effort in the
wet conditions but Kalou raced in to fire home the
rebound.
