So Jose Mourinho's fine record of always making it out of a European quarter-final continues. Thanks for looking in.
Sirigu goes up for it, Cech punches it away and then pushes Marquinhos' shot around his post with a fine save!
Azpilicueta's header on the edge of the box goes out to buy a few precious seconds, then Alex wins a corner...
A deflected ball across the box landed right in the striker's path, and his scuffed shot from six yards was enough to take it over the keeper and in!
Ba challenges the keeper, then Eto'o lashes a shot from close range into a defender - but the whistle goes for a block on the keeper.
A ball over the top towards Torres has just too much on it, but they are seeking him out all the time now.
Cahill rampages out of defence, loses the ball, then wins it back on halfway to keep the attack going.
A Chelsea attacking free kick is quickly back with PSG, with Lucas hitting a shot from 20 yards right at Cech following the break downfield.
Cavani wastes a great chance! It was Cabaye's diagonal ball, a nice touch with the Uruguayan's right, but he missed the target with his left and with Cech at his mercy!
Cavani and IVanovic tangle in the box, with the defender's back-header taking the ball away from from the striker before Maxwell pulls his shot across the face of goal.
The i,mpressive Willian finds Oscar on the right, and he whips in a teasing cross that is just too high for Ba.
A rare chance for Cavani, who runs onto a pass over the top before lashing a shot over Cech's bar with the Chelsea keeper watching it safely.
Wonderful control from Oscar brings down a 50 yard pass from Luiz on the left touchline, but again the PSG defence holds firm and the attack is thrown back up the pitch.
Schurrle cuts in from the right and gets a shot in off his left while going across the penalty area, but a deflection allows Sirigu to make an easy save.
With PSG down to 10 men, the defence copes with the corner until Cahill gets it back and earns another, but Cavani is back to head it away from the near post.
John Terry takes a blow but when he gets back on his feet, 'Mr Chelsea' gets an ovation from his adoring Stamford Bridge public.
A very entertaining 15 minutes since the resumption, and only the woodwork has denied Chelsea a lead with that vital away goal in the bank.
Ba and Torres are the attacking options on the Chelsea bench - will they get a go as they chase the game? In the meantime, Cavani's near-post header to a corner is flicked past Cech's post.
Lavezzi gets a lot of paceon the ball across the face of goal, and Cech does well to push it behind for a corner.
Ivanovic lunges at Matuidi on the edge of the box, on the left, and is booked - he'll miss Chelsea's next European game.
A fine move across the pitch from Chelsea, then Willian rolls the ball to Schurrle, who hits the bar with a shot from just inside the area! Unlucky for the substitute!
Lucas hits the deck under challenge from Terry but it looks like a dive and the ref waves play on. No booking, though.
Chelsea are pegging PSG back, then the French side win a free kick and, predictably, they take their time over it.
An early free for Chelsea is beaten away, then Azpilicueta is first to a long pass across field ahead of Lucas Moura.
Robert Smith via Twitter: "Chelsea playing with more purpose but the longer the match goes on chances will occur for PSG - prediction Chelsea 2 PSG 1"
The Chelsea crowd appeal for handball after the ball pings around the area just as the half time whistle blows, but so far so good.
Schurrle slices in from the left after a rapid break but three white shirts close the German down and snuff the attack out.
The goal and the spell since have been very lively and PSG look rattled - Petr Cech has had very little to do so far.
Lampard takes one for the team after he stops Lavezzi from getting away from him, the referee is the busiest man on the pitch at the moment.
Cavani is booked for standing right in front of Luiz as he tries to take a free kick, although he feels Luiz kicked it at him deliberately. He will miss PSG's next European game.
Thiago Silva needs treatment after a bad challenge from Eto'o after the pair chased the ball down near PSG's area. The PSG man is consoled by Eto'o and returns to action, but he's moving gingerly.
Lampard swings the free kick over from the left, and after a rebound Cahil takes a swing but the ball skews off yards to the right. But, it's all Chelsea right now.
Schurrle has claims for a penalty against Verratti, already on a yellow, as he goes to ground in the area, but it looked like he was running into the defender and it's not given.
Ivanovic's throw from the right was flicked on off Luiz's neck, and Schurrle flicked the ball past the keeper first time from dead centre, eight yards out for his first Champions League goal for the Blues. Halfway there!
That chance has lifted the home crowd, but the away fans are making plenty of noise as another deflected effort, from Oscar, loops safely into Sirigu's hands.
Lampard's free kick takes a wicked deflection off the wall from the angle, and Sirigu makes a fine save with his right hand after initially going to his left!
Chelsea need to impose themselves a bit more, but there are no signs of panic with over an hour left.
PSG fans giving it plenty of "olé" in a long spell on the ball for their team. Worrying signs for Chelsea on the own turf.
Luiz tries to launch an attack, but Cavani forces the Brazilian into a backpass - not much momentum for the home side yet.
PSG are taking turns to be patient now, keeping the ball away from Chelsea for a long passage of play that goes all across the park.
Another Chelsea attack breaks down when a poor Luiz pass towards Ivanovic is cut out easily by Maxwell.
Eto'o closes Sirigu down and barges the PSG keeper over, but the Portuguese referee Pedro Proenca blows for the foul.
Hazard, on the left, pulls the ball back to Lampard, who shoots but sees his effort blocked 20 yards out.
At the other end Lavezzi breaks away but is caught offside, rolling the ball in past Cech just for good measure.
Mostly Chelsea now, and they're being very patient and then Oscar squeezes the ball through to Eto'o from the left, with the striker's shot forcing a corner from close range.
Lampard gives it away in the centre circle, then fould Lucas he tries to make amends. PSG are in no hurry to get the game going again, unsurprisingly.
Not much from the home side yet in attack, but Alex gives away a free kick against his old side when he barges Hazard over 25 yards out on an angle.
Motta leads an attack that is broken down by the Chelsea area, then gets shoved away by Lampard as Chelsea regroup for a free kick while arguing with the referee.
Chelsea attack from the off, with Oscar forcing a throw in deep in PSG's half but the French side play their way out of defence.
Another confident Blue in Toby Day: "Hi, Chelsea to win tonight 4-3 on aggregate with Eto'o x 2 and Hazard or Lampard to score! Come on Blues!!!"
No-one has scored against Chelsea at Stamford Bridge since Man United's Javier Hernandez, eight games amd 732 minutes ago.
Opeyemi Idowu, Nigeria: "I would have preferred Mikel to Lampard or Luiz, because both of them are used to going forward while we (Chelsea) need a standby holding midfielder to stop PSG at the middle. But all the same I fancy Chelsea to win 2:0. Blues all the way..."
Peter Boase via Twitter: "Love the line-up! Think it is worth the risk for Eto'o, he loves scoring at the Bridge. Just hope he can make an impact!"
What do Chelsea fans think of Mourinho's team selection for tonight, and how are you feeling about your prospects? Let me know @TimOscroft or firstname.lastname@example.org.
The Blues overturned a 3-1 deficit against Napoli in 2012, claiming the last 16 tie with a 4-1 win after extra time. Of course if it ends at 3-1 tonight after extra time, we will go to penalties - but let's cross that bridge, that Stamford Bridge if you will, as and when we come to it.
Jamesss via Twitter: "Chelsea 2-0 we need to kill the game off as soon as possible and attack at their full backs as that seems to be the weak link."
PSG's bench: Douchez, Cabaye, Marquinhos, Menez, Digne, van der Wiel, Pastore. That last man struck with an eye-catching and potentially crucial goal late on last week - will he have an impact tonight?
The Chelsea bench is: Schwarzer, Cole, Mikel, Kalas, Torres, Schurrle, Ba. Torres and Schurrle played at the weekend, while the Matic and Salah, who also helped beat Stoke, are cup-tied.
Sky Sports' venerable commentator Martin Tyler said earlier that he thinks Chelsea will win tonight - but he wasn't certain if they will win by the right margin. PSG could park the bus, but is that in their nature? It's going to be a fascinating evening, that's for sure.
Liam Mortell: "I hope Ibra's absence will help Chelsea pull a win. I would love to see it go to penalties with Chelsea winning."
Earlier this week Mourinho shrugged off the absence of the injured Zlatan Ibrahimovich, and of his own missing he players he added, "Ramires is suspended. Nemanja Matic and Mohamed Salah cannot play for us in the Champions League - and we are not crying."
Harvey Goodliffe is in a confident mood: "If Hazard and Oscar are anywhere near their best I see no reason why we can't get at least two goals - we need to exploit their fullbacks in Jallet and Maxwell as they are undoubtedly the weakest points in the Paris team. Going for a 4-1 win. COYB". Get in touch via Twitter @TimOscroft or email@example.com. And let me know where in the world you're following the game from, there must be some far-flung Blues out there...
And we have PSG's starting XI as well: Sirigu, Jallet, Alex, Thiago Silva, Maxwell, Verratti, Thiago Motta, Moura, Matuidi, Lavezzi, Cavani.
Here is the Chelsea team for tonight: Cech, Ivanovic, Cahill, Terry, Azpilicueta, Luiz, Lampard, Willian, Oscar, Hazard, Eto'o
It's worth remembering that Jose Mourinho has never lost a European quarter-final tie, winning seven in the Champions League and one in the UEFA Cup.
So, Chelsea fans, what do you want to see from your team tonight? Who will be the key players? Feeling confident? Get in touch with via Twitter, @TimOscroft, or on email at firstname.lastname@example.org.
There are a number of permutations for Chelsea tonight given last week's loss in Paris, but that away goal may come in very handy. But, don't take my word for it, heed the words of the Special One (i.e. Jose Mourinho) himself: "Now we know that we need to win 2-0, 3-1, 4-1, 5-2. We know that we need a crazy result against Paris. We must be ready to go without fear, go at them and no problems and see what happens."
