Full-time: PORTO 0 - 1 CHELSEA. The Blues will advance to the knockout stage as group winners.
Play is disjointed in stoppage time.
Meireles fouls Malouda and this time Chelsea do run up the clock.
A delightful break by Porto that started from deep ends when Hulk's pass is too long for both of his intended targets. There will be three added minutes.
A Chelsea corner from Cole finds Ricardo Carvalho, who heads over the top.
Chelsea clear two waves of attacks.
Ivanovic blocks a cross for a corner.
Cole whips it in instead. Zhirkov's 18-yard header brings nothing of note and it's a goal-kick.
Chelsea win a corner. Perhaps a chance to eat up some time.
Raul Meireles receives a knockdown from Hulk and strikes it. Terry blocks well, before a second attempt is blocked by a Porto player.
Hulk dances his way through a number of would-be challengers and puts his left foot through the ball. Unfortunately for the home fans, Cech is right behind the low shot.
Ernesto Antonio Farias becomes the third and final replacement for Porto, slotting in for Sapunaru.
Raul Meireles fouls Malouda and it looks like frustration is creeping into Porto's play. Yellow card.
Hulk crosses for Rodriguez who acrobatically heads it just over. He screams for a penalty once more, claiming his shirt had been pulled.
The goal seems to have taken the steam out of the hosts. They are still pressing, but are lacking composure at present.
Local hero Deco is replaced to a rapture of applause. The former Barcelona man has endeavoured without effecting play too much. Joe Cole is on.
A stinging left wing cross is almost met by Hulk but it is Zhirkov who gets contact on the ball. Both men appear to have hold of each other and a foul may have been awarded either way.
Strange substitution, perhaps. The dangerous Belluschi makes way for Freddy Guarin.
PORTO 0 - 1 CHELSEA. Zhirkov breaks forward and knocks the ball on to Malouda, who has looked dangerous since the break. His cross is met by the head of ANELKA, who needs no second invitations from point blank range.
Michael Essien replaces the earlier booked Ballack.
Chelsea shout for a penalty as Zhirkov is bundled to the floor as he chases Deco's through pass. The referee ignores the claims.
A cross from Alvaro Pereira is met by Hulk but the ball is behind him. He volleys into row Z.
It's turning into a very even game now. Both sides are searching for a goal.
Malouda receives a pass at the byline and skips past his marker. He tries to pick out a team-mate in the middle, but the cross is cut out.
Givanildo Vieira Hulk appears off the bench in place of Varela.
Ballack is cautioned for bodychecking Rodriguez.
Porto break in numbers and with plenty of pace. The ball is sent left to Raul Meireles, who is caught in two minds and a cross-cum-shot flies into the arms of Cech.
Malouda is allowed to stretch his legs on the left and he sends the ball with pace across the six-yard area. Drogba is unable to get beyond his marker to poke the ball in. Nevertheless, this is better from Chelsea.
Drogba knocks the ball backwards to Deco who is just over 20 yards out. He has a go despite the opportunity being difficult, and it goes narrowly wide of Beto's right post.
Another Fernando-Drogba coming together in a similar position but the challenge is deemed fair.
Fernando is booked for a rash challenge on Drogba. The Ivory Coast man practices his theatrical rolling around like a baby act before picking himself up to take the set-piece. His shot crashes against the wall.
Malouda collapses in a heap and seemingly in plenty of pain. Chelsea continue and the Swedish official allows an advantage. But the ball is lost and instead of breaking, the hosts sportingly boot it out of play.
Chelsea look to assert some authority early by playing keep-ball.
The second half is underway.
Half-time: PORTO 0 - 0 CHELSEA. A bright start from Ancelotti's side has fizzled out and they will count themselves lucky not to be at least one goal down at the interval.
One added minute.
Sapunaru tries his luck from the best part of 30 yards but fails to get the desired connection on the ball. It flies across the face of goal.
Chelsea charge forward in numbers but Branislav Ivanovic's cross into the area is very disappointing and easily defended.
Cristian Sapunaru attempts to dribble his way right through a wall of white shirts and gets dispossessed.
A short break in play and perhaps a chance for Chelsea to regroup as they have let Porto take control of this game.
Neat interplay from the Chelsea front two presents Deco with a chance from 25 yards. He slices it high and wide.
Though perhaps still second best in midfield, the home side are breaking at will. Maybe its a matter of time before they get the lead. A free-kick in a dangerous position hits the Chelsea wall.
Deco's ball is poor once again and Beto gathers.
Porto break once more and Falcao has a go from range now. Cech saves low down.
Porto go close to an opener and it nearly came in spectacular fashion. Belluschi, who went close from range earlier, rattles the crossbar with a thunderous 25-yard attempt which dipped at the last.
Chelsea appear content to control this game in midfield, though they are resisting pushing for a goal.
Florent Malouda produces a high, rash challenge on Fernando but the referee refrains from producing the first card of the night.
Porto have a free-kick mid-way through the Chelsea half. It is tossed into the area, but Terry heads away well.
Zhirkov bursts forward and looks to get on the end of a ball to put him in behind the Porto back four. He struggles to control though and the ball runs harmlessly for a goal-kick.
Fernando Belluschi hits it from distance and it troubles Petr Cech, who has to resort to beating it away. The ball falls for a rebound, but the Chelsea stopper gets up to superbly deny Radamel Falcao of giving his side the lead.
Drogba gets his head on the delivery but it goes wide.
Drogba rides a couple of challenges to get to the edge of the area before pulling it back. The ball is worked wide to Michael Ballack, who cuts in on his left but produces a tame effort which is deflected away for a corner
The Blues, in their European change strip of all white this evening, win a corner. Deco takes, but the Portuguese playmaker fails to find the head of anybody and the ball trickles out of play at the opposite flag.
Anelka produces a stinging shot from an acute angle just outside the penalty area. It is moving in the air and Porto keeper Antonio Pimparel Beto is pleased just to beat it away
John Terry fails to clear a ball and it runs into the stride of the onrushing Silvestre Varela, but he is adjudged to have handled the ball.
It's been a positive opening from the hosts, who are attempting to catch the Premier League leaders out down the flanks.
Porto, in a change strip of orange, begin with the early possession. Jose Raul Meireles attempts to skip in behind the Chelsea back four, but is flagged offside.
Match official Jonas Eriksson signals for the proceedings to begin.
Deco is the front prong of Carlo Ancelotti's midfield diamond, with Didier Drogba and Nicolas Anelka leading the line.
A win for the visitors would ensure that they top Group D with a game to spare.
Yuri Zhirkov makes just his second start for the Blues since his summer arrival from CSKA Moscow.
