6.54pmThat is a really strong starting lineup! Arsene Wenger is clearly taking Bradford very seriously. The Frenchman has selected his first-choice goalkeeper, first-choice back four and apart from perhaps the absent Mikel Arteta, Olivier Giroud and Theo Walcott, it's a first-choice midfield and attack!
ARSENAL SUBS:Mannone, Jenkinson, Squillaci, Rosicky, Arteta, Oxlade-Chamberlain, Chamakh
6.58pmThe Gunners' two-goal man from the weekend, Arteta, drops to the bench and so does Alex Oxlade-Chamberlain.
BRADFORD SUBS:McLaughlin, Ravenhill, R.Jones, Connell, Hines, Turgott, Good
7.13pmBantams boss Phil Parkinson sticks with the same XI that edged out Torquay at the weekend, with Newcastle United loanee Curtis Good missing out.

7.26pmBack to the game at Valley Parade and tonight's game is the first time the two clubs have met in the League Cup.
7.27pmThe previous meeting between the clubs was a Premier League game at Highbury in January 2001, which Arsenal won 2-0.
7.28pmOverall, the sides have met 25 times in all competitions with Arsenal winning 11, Bradford nine and five draws.
7.31pmBradford have become the first club from the fourth tier to reach the last eight of this competition for six years.
7.34pmBradford manager Phil Parkinson tells Sky Sports News that his side have to be "disciplined" if they are to have any chance of causing an upset this evening.
7.35pmHis opposite number, Mr Wenger, says that he was able to select such a strong XI because their next game isn't until Monday.
7.37pmThis is Arsenal's 10th straight year in the last eight of this competition but we all know about their wait for a trophy. Can they end the drought this year?
16 minWow! A shock is on the cards as Jones's free kick is flicked to the back post where number 11 Gary Thompson smacks home on the volley first time. Great finish.
18 min"Sacked in the morning, you're getting sacked in the morning!" sing the Bradford fans to Wenger. The Gunners respond with a chorus of "There's only one Arsene Wenger!"
8.04pmGoal for Norwich in the other quarter-final tonight. Steve Morison puts the Canaries one-up on Villa.
8.05pmInstant equaliser for Villa! Brett Holman strokes home from the edge of the area to cancel out Morison's opener.
21 minSome world-class first-touch football between Cazorla and Wilshere almost presents the former with a chance to lay in Podolski but Jones nips in.
24 minAlmost a second for the home side as a Jones set piece causes more problems. The captain's corner is flicked goalwards at the near post and Gibbs has to hack to safety.
28 minFree kick for the Gunners 25 yards out as Cazorla is taken out when trying to play a one-two. Podolski likes the look of this...
29 minPodolski takes it on but that's straight into the wall.
30 minGreat feet from the impressive Wells in the area earns Bradford a corner but there's no danger as Mertesacker heads clear. Jones pumps the ball back in and Thompson gets away a shot with his back to goal but that's easy for Szczesny.
32 minWHEY chant the Bradford fans behind the Arsenal goal as Wilshere slices a volley on his weaker right foot miles wide.
8.17pmGoal on Wearside and Sunderland have taken a 2-0 lead as Steven Fletcher marks his return to the side with a clever backheel in the area. Class finish.
34 minSHOT! Gibbs chests a loose ball and then screams a volley goalwards that whistle's past Duke's right-hand post.
36 minThis is a worrying stat for Arsenal fans: The Gunners managed just one shot on target other than the penalties on Saturday against West Brom. Today they have none so far.
38 minOFF THE POST! Coquelin earns some space with a step over and then fires goalwards with his left. The shot beats Duke at his near post but not the frame of the goal.
40 minSHOT! Cazorla lets fly but it swerves inches wide of the post.
42 minWHAT A MISS! We've got a miss of the season contender from Gervinho! The Gunners work the ball nicely to Gibbs on the left and his cross-shot should be poked home by the Ivorian from a couple of yards but somehow he only gets a whisker of a touch on it and it rolls wide!
45 minCHANCE! So, so close to a Bradford second! Wells gets the better of Vermaelen and pokes a shot millimetres wide of the post.
8.35pmThis is a real surprise considering how strong an XI Wenger put out. Bradford could have had one more with Well's miss at the end of the half but Arsenal should at least be on the scoresheet with that Gervinho miss!
8.39pmIn the Premier League, Sunderland lead Reading 2-0 with goals from James McClean and Steven Fletcher. Click here to read our half-time report.
8.43pmMeanwhile, in the other quarter-final, Norwich and Villa are 1-1 at the break.
87 minThey've done it, at last. Cazorla's original corner is cleared straight back to him but his second delivery is much better and picks out Vermaelen at the back post to head home from a couple of yards!
89 minRemember, this game will go to extra time if the score stays like this at the whistle.
