Full report and reaction to follow. Thanks for all your thoughts. Goodbye.
Steaua Bucharest 1 Chelsea 0. Famous night for the Romanians, but Chelsea will have to play much better in the second leg if they are to progress.
Popa tries his luck from distance, but ball flies just wide. Wastes more time for the Romanians.
Rusescu goes off, to be replaced by Gardos. His job is done.
Four added minutes...
Lampard has his first effort of the game, but fires well wide from distance. One of his poorest showings of the season.
Really nice move from Steaua, passing the ball around well, but the final cross is overhit by Popa, rolling straight to Cech.
David Luiz fires a free-kick from distance. Gets incredible power on it, but it flies just over. Impressive from that range.
Marin does well to create space for a shot, cutting inside and firing the ball nearpost, but it is palmed away by Tatarusanu.
The impressive Tanase goes off, to be replaced by Leandro Tatu.
Mata tries to thread the ball through, but it is easily cut out. Story of the night for Chelsea.
Toby Day tries to rally his troops. "Hi, COME ON CHELSEA!!! They should try and at least get 1 goal! I want CHELSEA to win 2-1!!!"
Chorus of whistles around the ground as Chelsea pass the ball around. In fat, it could be the Blues' fans as their side severely lack in creativity.
Marko Marin comes on for Chelsea, in place of Hazard, who struggled all evening.
Hazard finds space at the back post, running onto a Torres flick, but he can only fire over from the tight angle.
Rusescu runs at David Luiz, but the Chelsea defender does well to step across and shield the ball out.
Torres again surrenders the ball too easily. Looks like he wants to be elsewhere. Very poor from the talented Spaniard.
Very poor from Chelsea. Just giving the ball away far too often. They are capable of much better than this.
Cech has to rush from his goal to cut out long ball over the top. Chipciu adjudged to be offisde however.
Mikel goes into the book for a late challenge. A little clumsy if anything.
Juan Mata comes on in place of the very ineffective Benayoun. Needs to inject abit of quality into the game.
Sean Hawdon also far from happy: "Chelsea are having the worst game I've seen them play for a long time."
Matt Calory has been touch via email: "Aside from Paul Scholes, Frank Lampard has been the best midfielder in Prem history. Not showing it tonight. Looks a little fat!"
Tanase again in space after being picked out by Chipciu, but blazes the ball way over the bar.
Scrappy at the moment. Chelsea trying to get the ball down and play, but still being stifled by the Romanians.
Prepelita comes on for Steaua, with Pintili making way.
Ball falls to Tanase on the edge of the box, who lashes the bouncing ball wide of Cech's goal.
Hazrad looks set to pull the trigger, but stumbles at the last moment. Unfortunate.
Chelsea really struggling to get going. Cannot get hold of the ball at the moment. Don't look like European champions at the moment!
Tanase sprays the ball wide to Latovlevici, but his effort goes way over the top. Poor from a good promising position.
Pintili receives yellow card for leaving his foot in on John Terry.
Tanase almost gets in, but but his shot is blocked. Chelsea must up their game, and fast!
Kenny isn't confident on the email: "Chelsea clueless under Rafa & will go down 2 nil."
Second-half is underway!
Hiruy has been in touch via Twitter: "Chelsea has been atrocious so far, we need a spark ASAP! Lets go Blues."
We apologise of you have had trouble receiving this commentary. We have been having severe technical problems, but should be ok for the second-half!
Steaua Bucharest 1 Chelsea 0. Chelsea much better after going behind. Benitez will feel penalty was harsh, but Steaua arguably deserve their lead.
Great effort from Torres. Has had limited service, but lofted ball over the top is taken down well by the Spaniard, who hits a fierce shot too close to keeper Tatarusanu.
Hazard in a great position to pull it back, but his touch his heavy and the ball runs out for a goal-kick.
Tanase with the strike from distance. Plenty of power, but lacking in direction.
SAVE!!! Tatarusanu gets a good left hand to a weak Benayoun strike when in space on the edge of the box. Great move from the Blues.
Chelsea must up their game, sat back far too much so far. Need to support Torres up front!
GOAL!!! Steaua Bucharest 1 Chelsea 0. Rusescu Penalty. Cech almost gets to it, but Rusescu put sufficient power on his spot-kick to beat him.
Rusescu looks odds-on to get a head to the ball eight yards out, but Bertrand impedes him. Penalty.
PENALTY TO STEAUA!!!
Torres runs at the Steaua backline, almost gets in, but a last ditch challenge denies him.
Very cagey affair at the moment, with both sides struggling to put a meaningful attack together.
Oscar almost in, but Bourceanu gets across to dispossess the Brazilian. Goal-kick.
Ivanovic gets his head to it, but the ball rolls harmlessly wide. Got up to early.
Much better delivery, but Szukala gets his head to it first and flicks clear. Corner.
Another free-kick to Chelsea. This time Torres is fouled. Great position for Lampard to cross.
Lampard with it, but it is cleared. Terry hooks it back in, but is cleared once again.
Free-kick Chelsea for a foul on David Luiz. Good chance to put the ball in the box.
Goal-kick to Chelsea as Bertrand sheppards the ball out of play. Good, strong defending.
The Spaniard almost gets in, but doesn't quite have the legs. Better from the Blues.
Torres looking very isolated up front. May have to pick off scraps this evening.
Bourceanu with the long ball for Rusescu to chase, but he can't quite latch onto the pass.
Mikel this time prevents Steaua from breaking. Very much all the home side at the moment.
Ivanovic with the block, when Chipciu looking dangerous once again.
Chelsea now on the attack, with Oscar trying to create from deep.
Lots of pessession for Steaua, but Chelsea pressing well, keeping it all in their half.
Free-kick to Chelsea on the half-way line, lumped into the box, and is cleared.
Bertrand again in the way, but gets a kick in the shin for his troubles.
Corner again to Steaua as Ryan Bertrand makes the interception.
Chipcui has the first strike at goal, but the ball trickles harmlessly wide.
Oscar with the chance to carry the ball forward, but his pass is wayward.
Torres chases down the ball, but it is easily cleared. Steaua look vulnerable at the back.
Corner already for Steaua!
We are underway...
Steaua Bucharest have conceded just four goals in 11 home games this season, and Sky Bet have boosted their price to win 1-0 to 8/1. Cristian Tanase to score first is a 14/1 shot, while Yossi Benayoun to score first in a 2-0 Chelsea win is a tempting 75/1.
The man in the middle is Sergey Karasev from Ukraine.
The teams are in the tunnel!
John Terry is back in the side for the Blues, despite spending much of the Blues' recent fixtures on the bench.
For Steaua, Raul Rusescu could be the dangerman. He is the leading scorer in Romania, and leads their attack tonight.
This is Chelsea's 50th game this season already, and with Sunday's massive clash with Manchester United to come, is it surprising that Benitez has named such a strong side?
Moses and Ramires remain back in London to rest. Ba is ineligible. Ashley Cole is on the bench.
Strong Blues team named by Rafa Benitez, with five changes made from the weekend's win against West Brom.
Steaua XI: Tatarusanu; Rapa, Zukala, Chiriches, Latovlevici; Pintilii, Bourceanu, Tanase; Popa, Rusescu, Chipiciu
Chelsea XI: Cech; Azpilicueta, Cahill, Terry, Bertrand; Mikel, Lampard; Benayoun, Oscar, Hazard; Torres.
The teams are in... Fernando Torres starts!
