Thanks for joining me for today's commentary, I hope you enjoyed the coverage. Enjoy the rest of the weekend's football, I'l catch you next time.
So once again John Terry steps up when under pressure. That was all too easy for Chelsea, with QPR extremely tame going forward.
Not much time left now as Torres is flagged offside. Late break from QPR though...the ball falls to Luke Young on the edge of the area and he has a crack...well saved by Cech! Wright-Phillips blazes the follow-up over!
Barton steps up to deliver another free-kick into the Chelsea box but Cech confidently comes out to claim. Another tame set piece play.
Macheda slips at the crucial moment when looking to latch on to a flick-on. He has been anonymous since his introduction.
One has to praise John Terry for his display today, been rock solid and brought the ball out of defence well.
Andre Villas-Boas watches as his side play keep ball in the final minutes. Will Rangers manage a chance in this game?!
Another woeful cross from Barton can't beat the first man and despite a QPR player going down on the edge of the area, Chelsea clear their lines.
Poor defending from David Luiz sees the Brazilian dally on the touchline before pulling down Rob Hulse. Chance from this free-kick maybe.
Unorthodox control from Wright-Phillips in midfield gets QPR possession but instead of looking to build they go back to Kenny - time is running out!
Barton's cross is way overhit and that's a complete waste. Set pieces look like the only method of scoring for Rangers so his manager will not be happy.
Clint Hill does well to clear his lines and QPR launch a quick counter, resulting in a corner on the right.
So can Rob Hulse pose a threat to the Chelsea defence in the closing stages? He will certainly be a physical presence.
It looks pretty serious, let's hope not though, and Romeu is preparing to be introduced to the fray.
The Brazilian must be in some discomfort down there because they aren't moving him as yet and Chelsea are preparing to make a change.
Pause in play here while Ramires receives treatment on an injury. The stretcher is on and it looks like he's coming off.
Ashley Cole goes into the book for a foul on Wright-Phillips. From the free-kick Cech comes out to punch well and Buzsaky's shot is charged down.
It really is extremely comfortable at the moment for Chelsea. QPR can barely string two passes together, getting outclassed.
Chelsea deliberately trying to slow the tempo down now with just over 20 minutes remaining in this contest.
Wright-Phillips looks to get things going down the right touchline but he is forced out of play. Not been his best game.
Chants of 'Anton what's the score?' from the Chelsea fans. QPR need to make a tactical change in my opinion to claw themselves back into contention.
Hall can't clear his lines under pressure from Malouda and at the moment Chelsea are camped in the QPR half, Sturridge winning a corner.
'Que sera sera, we're going to Wembley' is the chant from the Chelsea supporters. Not over yet though.
If the penalty was perhaps harsh, to be fair to Chelsea they deserve their lead? What have Rangers got in the tank now?
Well that should force QPR to come out and be a bit more expansive now, but the home fans aren't happy.
The Spaniard smashes the penalty into the bottom corner but it was a controversial spot-kick in the first place - Sturridge tumbling under Clint Hill's challenge. Looked pretty soft.
Sturridge goes down in the area under the challenge of Hill but it's a corner says referee Mike Dean. Good defending in the end then and Kenny eventually claims the corner.
Wright-Phillips picks it up wide right but his low cross is easily cleared by Meireles. His delivery has been poor so far.
Cech comes out of his area in the right channel and slices his clearance straight out of play. The Rangers fans find their voice once more.
Kenny hoofs the ball forward looking for Macheda, but that's meat and drink for the Chelsea defence. The Italian has hardly touched it so far.
Pressure from Chelsea down the left as Ashley Cole's low cross is cleared. David Luiz then has a crack from long range...but it flies wide.
That was more like the Torres of old and one positive Chelsea can take from today is the fact he has looked extremely sharp.
Great footwork from Torres inside the area to beat two men and then lay the ball off for Sturridge...who blazes over the bar! Good chance that.
Corner to Chelsea as Hall slides in to block Malouda's cross. They are slowly but surely cranking the pressure up.
Mata is in space inside the area but his shot on the turn is saved - the flag was up for offside anyhow.
The pace is still there in this game and the half has started as the first ended, with Chelsea dominating possession.
Bright start to the half for the away side and Sturridge tries a snapshot inside the area...blocked well.
Chelsea advance down he right early on and Ramires lifts a cross in looking for Torres...over his head.
So Mark Hughes makes a change at the break with Macheda coming on - he could provide the attacking spark QPR need.
Rayhan Choudhury Tweets to say: "Malouda ZERO in midfield. Push him to wings. Mata to play in Lamp's position. Doesn't take a rocket scientist to fig that out!"
Well an interesting, hard-fought first period there, with a few half-chances for Chelsea. QPR have showed little so far.
Late Chelsea pressure down the left as Torres rifles in a dangerous cross...headed clear at the last.
Good recovery from Clint Hill to get back and clear his lines there, QPR looking to keep it tight at the moment.
Luke Young puts the ball out of play under pressure from Torres and Chelsea build again. Eventually the ball is pulled back to Malouda on the edge of the area...but he drags his shot wide.
Malouda lifts in a cross from the left but despite the best efforts of Torres it is over the Spaniard's head.
Are we going to see a goal before half-time? Chelsea are beginning to turn the screw at the end of this first 45.
Mata sends in a free-kick from the left touchline and it's aimed at Terry...but the Chelsea skipper is well marked and can't get contact on it.
Nice interplay from Sturrdge and Chelsea down the right and the Brazilian is slipped into the area...but his cross flashes over the heads of his team-mates in the box.
Barton whips the corner to the near post but there is Ramires to head clear well. There was no Rangers player challenging for that.
Sturridge gives it away this time and Tommy Smith brings the ball forward. QPR win a corner after pressing down the left.
Meireles gives the ball away in his own half and QPR sweep forward with pace, it's played out to Wright-Phillips down the left who cuts inside and has a crack...always going over.
Another set piece pumped long by Rangers but it's pretty aimless and Cole heads clear. Mike Dean is then on the receiving end of catcalls from the home crowd after giving a decision Chelsea's way in the centre circle.
Nice hold-up play from Torres down the left to keep a Chelsea move alive, he feeds the ball across and there is Meireles to pull the trigger...not too far wide.
Ferdinand knocks a rather hopeful ball out wide for Jamie Mackie but he can't latch onto it. Goal-kick.
Nice move from Villas-Boas' men ends in Ashley Cole lifting a ball to the far post from the edge of the area, it's aimed for Sturridge but just has too much on it.
So about 15 minutes until the break and nothing much between this sides, despite Chelsea on top in terms of possession.
Terry brings the ball out of defence but his ball through the left channel is too powerful this time.
Yellow card for Shaun Wright-Phillips following a slightly reckless challenge on Meireles, nothing too bad though. Just before that Malouda wasted a good crossing chance at the other end.
Nice play from Barton in midfield as he turns away from two players and sprays a pass wide left, again QPR can't create anything though.
It's all very neat and tidy from Chelsea in midfield but QPR have looked relatively comfortable in defence so far.
Marauding run forward from David Luiz and the Brazilian advances into the opposition area with great skill, before his central pass is intercepted.
Florent Malouda sends in a dangerous low ball from the left and Paddy Kenny has to be alert to get down and claim, with Torres lurking.
I'm happy to say so far there have been no poor challenges, but there has also been a lack of goalmouth action.
From the resulting corner John Terry heads the ball back across goal and Luiz attempts a spectacular overhead kick - well over.
Cute ball forward from Terry and it finds Ashley Cole on the by-line, he sends in a first-time cross, turned behind by Hall.
Buzsaky whips in a good cross from the right but no-one in blue and white can turn it goalwards. QPR need a bit more sharpness in the final third.
Luke Young is up against Ashley Cole and can't beat Chelsea's left-back in an attacking position. Good battling from both players though.
Ivanovic does well to hang a looping ball up to the far post with Torres looking to get on the end of it...headed away.
Barton whips in a decent cross from wide left, aiming at Ferdinand, but David Luiz is there to head clear. Good defending.
Ramires isn't happy after Mike Dean penalises him for a foul in the QPR half. At the other end it's a free-kick for Mark Hughes' men - crossing opportunity.
Speculative effort on the half-volley from Barton...never troubling Cech but a decent try nonetheless.
Long ball upfield from Rangers and Helguson flicks it on...good clearance from Terry. QPR coming into the game a bit more.
That was a decent chance for Mata but credit for the swift counter-attack. From the corner Ramires can't get decisive contact on the cross, goal-kick.
Good save Kenny to deny Mata! Quick break from the Blues following a QPR free-kick at the other end, but the Spaniard's low shot is turned away by the keeper!
Chelsea are dominating but Sturridge can't quite control a fizzing pass from Ramires. Some respite for QPR.
No chances as yet and neither goalkeeper has been tested. Andre Villas-Boas will be the happier of the two managers though.
Meireles is the one looking to get things going for the away side, and they are dominating possession. Sturridge has a crack from the left...way wide.
John Terry hasn't been phased by the boos at all, but that doesn't surprise me. One thing you can say about the Chelsea captain is that off-field problems don't hamper his performances.
Frantic pace to the game so far, as expected in a derby cup tie. Helguson looks to loft a ball over the top but it is too powerful and through to Cech.
Shaun Wright-Phillips with the chance to skip forward now but he checks back as Rangers try and retain possession and get a foothold in the game.
You wonder how long the boos for Terry will last - it's quite tiring if done for 90 minutes one imagines.
Ashley Cole slips in Malouda with a delightful pass but the Frenchman's cross is comfortably over Torres' head. QPR chasing shadows at the moment.
Decent start from Chelsea as Sturridge advances down the right flank, he cuts inside but there is Ferdinand to intercept.
Chelsea knocking it around well in the early stages here as Terry lofts a ball forward for Torres, who is offside.
Cracking atmosphere inside the ground and John Terry is the target for the home fans, but he makes a good challenge inside his own area.
Forget all the hype about a pre-match handshake - the two teams have run straight onto the pitch without the usual line-up formalities. Terry and Barton shake in the centre circle though.
Yes let's hope there's no trouble today - big police presence at Loftus Road and we're not far from kick-off now.
Steph from Monchengladbach in Germany writes: "I am hoping for a cracking match!! As a Chelsea fan hoping for a win...but tipping a 2-2 draw. And a win in the replay. Hope no trouble before ..during..and after the match. Come on you Blues!"
John Terry has already been roundly booed by the home supporters here, but Chelsea fans of course gave their captain a great reception when he came out for the warm-up.
Chelsea: Cech; Ivanovic, David Luiz, Terry, Cole; Ramires, Meireles, Malouda; Sturridge, Torres, Mata

All eyes will be on the John Terry-Anton Ferdinand handshake before kick-off, but let's not forget that is a mere sideshow - there is a place in the FA Cup fifth round at stake.
So we've had 'bullets' in the post ahead of this one - what next, a horse's head or a box of dead fish?
Morning everyone, not usual that I say that on commentary duty, hope you're ready for a cracker of a Cup tie at Loftus Road today.
