That is all from me for this evening. Thanks for joining me. A full report and reaction will follow shortly.
And that is it! Newcastle have come to the home of the holders with a young, inexperienced side and dumped out the holders. Few saw this coming, but you cannot take anything away from Alan Pardew's side. They were as superb. City were dire.
Newcastle throw bodies in front of shots from Aguero and Milner before Elliot comes out to claim a cross from Navas.
Sissoko runs the ball deep into the City half and does superbly to win his side a corner. Newcastle take it short and eat into even more time.
Ameobi is booked for Newcastle just as the board is raised showing six minutes of added time. City still have a slim chance.
Newcastle are so close to scoring a third as a free-kick is swung in to the box for Ameobi, who gets his head to the ball and somehow keeps it alive to swing a cross towards Riviere, but the sub cannot make contact in the box.
The finishing line is in sight for Newcastle now. They have done so much hard work and they have just a few minutes more to do to record a famous victory.
Another golden chance falls City's way as Navas is set up by Jovetic but the winger's shot flies wide of goal. Her should have scored.
What a block that is from Taylor! City look certain to score as Dzeko is given a clear sight of goal following a cross from the right but Taylor throws himself forward to block the striker's goal-bound shot. That sums Newcastle up tonight. Awesome stuff.
Desperate times for City. Milner has plenty of space in the box to cross but his delivery beats everyone and flies out for a goal-kick.
GOAL!!!!!! Unbelievable! Newcastle have soaked up constant pressure but now they are firmly in the box seat thanks to Sissoko, who nips into the box before flicking his shot past Caballero. The away supporters are going nuts!
City have a well-placed free-kick, but Kolarov plants his 25-yard effort straight into the hands of Elliot.
In amongst all the penalty controversy, Mangala picked up a yellow card for a body check on a Newcastle player.
Big decision! Newcastle think they should have a penalty as Obertan drives into the box ahead of Kolarov, who slides in and fells him. The referee waves the penalty protests away... but replays show he got that wrong. Kolarov didn't get the ball, he got the man.
There isn't much room for City to exploit near the Newcastle box but then the home side are hardly moving the ball fast or accurately enough to create any openings.
A double change for Newcastle sees Janmaat and Armstrong come off for Sissoko and Riviere. That is Pardew's full lot of substitutions done.
Abeid has taken a big forearm from Mangala and is out for the count. He needs treatment and Newcastle get a much-needed breather.
This prompts a change as Toure trots off to be replaced by Navas. Will this give City greater penetration?
City come forward again but Jovetic's flicked pass cannot find Milner in the box and the ball bobbles out of play.
Kolarov picks out Dzeko with a neat pass inside but the striker's shot from 25 yards is blocked by the diving Dummett.
The ball is in the City net from an Obertan shot (and a really good one as well), but he was offside when the pass forward found him in the box.
Kolarov has another chance to cross but his delivery is woeful and floats over the goal and behind for a goal-kick. That is just lazy.
That is better from the home side, as they put Kolarov clear down the left from a free-kick but his fizzing cross flies past everyone in the box. All it needed was a touch.
Toure sums up City's display so far by putting a pass straight out of play in the Newcastle half. They have been well short of their best in the first 50 minutes.
Kolarov is doing some serious grimacing as his arm is bandaged. It looks like he is going to be OK, though.
Kolarov has taken a knock on his elbow and requires treatment. Another injury is the last thing City need.
Rolando Aarons to open the scoring and Newcastle to win in 90 minutes was 40-1 before the game. I know because I told you so about an hour ago. To check out the latest betting prices have a look here: http://www.skybet.com/football/capital-one-cup/event/17126078.
Take a bow Newcastle. They have produced a really good half to contain a vastly more experienced City side. And when their chance came they took it. City have had plenty of the ball but need to do more with it in the second half.
Oh! Newcastle are inches away from doubling their lead. Armstrong slides in to meet a low cross but his effort deflects off his sliding marker Dimichelis and back off the striker before going just wide.
Toure forces a corner that Milner delivers and Mangala rises to meet with a powerful header but he cannot direct it on target.
City are piling on the pressure. They force a corner that Nasri delivers and Dzeko meets but puts his header wide of the goal.
Fourminutes until the break and Newcastle continue to frustrate City. Jovetic tries to thread a pass into the boox after charging forward but Haidara does well to cut it out.
Nasri has time to pick put a cross on the left but again he fails to beat the first man. He may be returning from injury but the French midfielder is much better than that.
Newcastle have to resist a concerted period of City pressure, with crosses fired over from both sides, but the away side do well and hold firm.
Newcastle should be 2-0 up. Simply as that. The corner is slung over and finds Dummett completely unmarked to fire a volley on goal, but Caballero gets down to save with his feet. It is a good save, but Dummett should have buried that.
City break but Nasri is unable to do anything with it as his low cross from the right is poorly placed and easily cleared. It allows Newcastle to charge down the other end and force a corner...
The half-hour mark passes and Newcastle can be very happy with their night's work so far. The have the game's only goal and have dealt reasonably well with what City have thrown at them.
Oh! So close for City! Coloccini has just got away with one as he slices Kolarov's cross from the left against his own post. Soon after, Jovetic fires a shot horribly wide at the back post following a corner from the right. Newcastle survive.
Dummett goes into the book for a foul on Sagna. That's the first booking of the game. It was a full-blooded tackle, and definitely a mis-timed one.
Janmaat unleashes a thunderbolt from range, which Caballero has to palm into the air before gathering. That was travelling.
What a save from Elliot! A City corner is taken short for Nasri to cross and find Jovetic at the far post but Elliot does superbly to get down and block the shot from the striker, who has two more sniffs but cannot get any power on either to test the keeper again.
Chris Green, via email: 'Just goes to show that just because the manager has decided to field an inexperienced team, it doesn't mean your side don't have a chance of causing an upset. There would be no point of turning up to the game if you were fearing the worst. Anything is possible in cup football - so having belief is key.'
Newcastle are working extremely hard to stay compact with City applying pressure. A cross from the left is over the head of Dzeko but the home side come again. However, Jovetic can only poke a shot wide from inside the box.
Fernandinho digs out a shot from range but pulls it way past the post. Poor effort from the City midfielder.
City look to break but Coloccini slides in to deny Jovetic on the left-hand touchline, much to the delight of the travelling fans. Newcastle are really up for this.
This kid Aarons has got a real yard on him. He skins Sagna and gets a nudge on the edge of the box to give Newcastle a dangerous free-kick. Taylor is over it...
Newcastle enjoy a bit of possession in the City half but Obertan cannot force out a cross from the right. That goal has given the away side some clear belief.
Another early blow for City sees Silva (who was injured a couple of minutes ago but tried to play on) leave the action. However, as replacements go, Nasri is not a bad one.
GOAL!!!!! How about this then? Newcastle - the inexperienced underdogs - lead! It is young Aarons with the goal. He nips into the box and away from Mangala. It is a tight angle but he finishes low under Caballero. This just got very interesting.
Silva has to leave the pitch for treatment. Meanwhile, Toure hits the free-kick but plants it into the stand behind the goal. That is a waste.
Silva is fouled on the edge of the box by Taylor and the Newcastle goal has a serious threat pending...
Newcastle get a free-kick near the halfway line but waste the chance to forge something from it by hitting long and straight into the arms of City keeper Caballero.
City on the front foot straight away, but Jovetic's forward pass to Dzeko in the box is cut out by a Newcastle head.
The teams are on the way out. In just a few minutes time we will have a whole game of football for you...
Ricky Stacey has emailed, saying: 'We are on our best form this season and we field that side... hope for a shock win for the toon but think city have this all day long.'
Ryan Hutchinson says: 'Weaker side chosen by the toon tonight, but I think our morale will edge us past them tonight! 0-1 NEWCASTLE!'
If you fancy putting your money where your mouth you can head on over to Sky Bet to take advantage of some of the offers on, er, offer, including Rolando Aarons to score and Newcastle to win in 90 mins at 40-1... http://www.skybet.com/football/capital-one-cup/event/17126078.
Pardew has been chatting to our reporters about his team selection. Here is what he had to say: 'At Spurs in the second half we found ourselves and we need to continue that tonight. The team is not as strong as I would like because of the way the TV schedule has placed us. We have put a lot of pace in the team so hopefully if they over-commit we can capitalise.'
Hang on, though, I've got an encouraging Newcastle stat for you... Alan Pardew's side have won seven of their last nine League Cup games away from home. This includes winning all of the last three.
With 29 goals in their last seven League Cup ties, Manchester City are averaging four goals a game. Bit ominous.
Toon fan Michael writes: 'Very disappointed in Pardew's team tonight! After Sunday's 2nd half felt this game was very winnable but can't see it now...another year without success. I'll say 3-0'
Not wishing to make the mood worse for Newcastle, but they haven't scored against Manchester City in their last five meetings in all competitions. Plus, in last year's League Cup fourth round they were beaten 2-0 after extra time at home by... Manchester City.
But there remains some confident Newcastle supporters, such as Chris, who sent in this: 'NUFC morale will be high after the Tottenham game and although we have sided a weakened side, I think we can sneak a result from a complacent city side tonight. 0-2 to NUFC.'
Pardew has got the Newcastle fans praying. This is from Kev James: 'Cannot believe Pardew ...what's he doing ...anyways gotta pray for 2-2 draw and a win on penalties for the toon'
History suggests that a home win is likely as Newcastle haven't won against their opponents in Manchester since September 2000, when Alan Shearer scored the only goal in a 1-0 league win at former ground Maine Road.
United, who have never progressed beyond the fourth round of a domestic competition under Pardew, have already featured in two Capital One Cup fixtures this season - away wins over Gillingham and Crystal Palace.
Newcastle arrive at the Etihad Stadium in their best form of the season. They are unbeaten in October and have won their last two games, at home against Leicester and away at Tottenham on Sunday.
However, they have been red hot in their one League Cup tie this campaign, putting seven unanswered goals past Championship side Sheffield Wednesday in the last round.
They have not got the defence of their Premier League crown off to the best start, with Manuel Pellegrini's men suffering a third league defeat of the season at West Ham on Saturday.
City are, of course, defending this trophy having beaten Sunderland in last year's final as part of a domestic league and cup double.
And George Stocker has followed suit with a confident prediction of a City win: 'I'm going to have to go for a home win tonight. It's been difficult to tell whether or not we will turn up this season before games, but i think the players seriously want to retain the trophy. It's definitely a winnable competition and i think that's reflected in the team sheet. City to win 2-0 with Jovetic to get on the score sheet.'
Tony Hassall has sent us his prediction: 'Think it will be a whitewash (or rather bluewash) by City tonight. Let's go for a 6-0. (Which means Newcastle will probably win 1-0 in extra time)'
One big plus for Newcastle is the return of injury-hit midfielder Ryan Taylor, who is making his first appearance since August 2012.
In contrast, Newcastle's is an inexperienced side. City have got to be even bigger favourites to reach the last eight now.
That is a pretty strong Manchester City side. David Silva, Yaya Toure, Edin Dzeko, James Milner, Stevan Jovetic. Newcastle have got their work cut out. In addition, Samir Nasri makes his return from injury on the City bench.
Newcastle starting XI: Elliot, Janmaat, Coloccini, Dummett, Haidara, R.Taylor, Abeid, Colback, Obertan, Armstrong, Aarons.
Manchester City starting XI: Caballero, Sagna, Demichelis, Mangala, Kolarov, Milner, Toure, Fernandinho, Silva, Jovetic, Dzeko.
