Thanks for tuning in tonight, there's been some great feedback. Stay with us for the full report and all the reaction.
The League Two club win 3-4 on aggregate to book their place in the final against either Swansea or Chelsea. They weathered the storm and they've got their rewards.
Understandably nervy defending from Bradford as they scramble to clear another Villa ball into the box...
There's a late Bradford corner which is taken short but Villa get it away, with Given lofting a long ball up the pitch.
The corner very nearly falls to Bent who might've been able to slot it home from a tricky angle but it just slips past the striker.
Four minutes of stoppage time are added - not what Bradford will be wanting to hear. Villa win a corner on the left.
Turgott's risky move proved costly as it allowed Given's long kick to find Weimann, who rounded the Bradford defence to slide home into an empty net.

Doyle gets gingerly to his feet as the Bantams prepare to take a free-kick in midfield but Clark is there to meet the long delivery towards the Villa goal.
Lowton blasts a cross into the box but Doyle gets it away at the second attempt. Vlaar tries again but it's Darby there this time to clear.
Jones lifts the corner in and Hanson dives in for it but he can't repeat his heroics as the Villa defence hold firm.
Wells wins a corner for Bradford off Vlaar and there's another opportunity for the visitors in these late stages.
Weimann gets away down the right for Villa as he brings some fresh impetus to their attack but his cross is a wayward one.
Benteke charges into the Bradford box but McArdle gets there first to ease the pressure. Villa are beginning to ramp up the heat again.
Agbonlahor beats Darby to plant a cross into the box from the left but it's hacked away by McHugh. Hanson and Vlaar battle to win a long ball into the Bradford end.

Benteke won't let Darby see the ball out in the left corner and hoofs it into midfield. Hanson catches Vlaar in the face and the defender goes down but is soon back on his feet.
A quick line from Sky Bet - Aston Villa are now 7/2 to make the final with substitute Darren Bent 7/2 to make the desired impact by netting next.

Bradford try to mount something at the other end and Wells wins a throw on the right. The visitors are looking a bit more confident.
Bennett plants a great ball into the box for Villa which McHugh does well to deal with. Benteke leaps to reach the resulting corner but it goes behind for a goal-kick.
'You're getting sacked in the morning' is the chant ringing out through Villa Park as the pressure increases on Villa boss Lambert.
Villa have a big job on their hands once again now. Bradford win a throw in midfield and are in no hurry to take it after restoring their advantage.

Many thanks for all your feedback, sorry I couldn't publish them all but it's almost time to get back underway. Time to find out if Bradford can hold on...

Nick Cary has been underwhelmed with Bradford so far - 'Really hoping to see Bradford at Wembley. Playing like they are, I cannot see that. Really poor defending and unable to really clear the ball.'

@carlos_11 - 'villa need to win this game. For morale if nothing else! And so the guys at work leave me alone for a week!'

A late word from Dan Joyce - 'Can't wait for tonight's game, from a neutral point of view I'd love to see Bradford reach the final, this is what cup competitions are all about! I think/hope villa to win 2-1 to see Bradford through, they deserve it after seeing off Wigan and Arsenal already!!'
Enjoying your feedback, keep it coming at half-time. Just five minutes to go until kick-off - should be a good one tonight, for the neutral as well.
@Nicibean tweeted - 'Can't say I have complete confidence we'll pull off the upset but it's a massive achievement regardless!'
Brian A Cook wrote to say - 'Glad to see Stephen Ireland starting, one of our most experienced players. I have mixed feelings tonight. If we win it is a trip to Wembley but will we do a 'Blues' and not concentrate on the important thing the league. Obviously, conversely if we lose we can concentrate on the league although we will have the shame of going out to a 2nd division side. Villa Supporter over 60 years.'
@br0hank tweeted - 'definitely going for the Bantams here. 1-1 with Bentleke and Wells scoring. Duke to be the motm.'
Thomas Armitage has written in - 'My name is Thomas I'm going with 1-0 Aston villa but bradford qualifying.'
A word from our friends at Sky Bet - Aston Villa are attracting the majority of the backing tonight with the Premier League side 1/3 to win and 10/11 to qualify. Bradford are 13/2 to progress in style with a win while a betting is also available on either side progressing in extra-time or on penalties.
Richard Moore, writing in all the way from Australia, says - 'I've followed the Bantams from my teen years and have endured a multi-decade roller coaster ride between winning promotion out of the lower levels, the horrific fire, the top flight and back down again. Bradford can do it today as they have the belief and Villa are shaky. I'll go for an in-form lower level team against a struggling premier league mob any day. Go the Bantams.'
Jon Crutchley has been back in touch - 'Looking for big start from three villans agbonlahor to be motm and will defo score tonight!'
In terms of recent form, the worry for Bradford is that they've lost their two games since their first leg success, while Villa drew with local rivals West Brom at the weekend.
@_thescore tweeted - 'a Blues fan with my Bradford shirt on tonight! Still reckon Villa will sneak through though, think they may get early goal.'
Peter Robinson wrote in - 'Ex-pat Villa fan checking in from a freezing cold Chicago. Going for Villa to some how keep a clean sheet and win 2-0 and go through on away goals after extra time. Well I hope anyway. UTV.'
Defeat in the first leg at Bradford increased the heat on Villa boss Paul Lambert and redeeming this tie could be just the boost the flagging Midlanders need - with either Swansea or Chelsea awaiting them in the final.
The Bantams have a chance to make history tonight - if they do the business they'll become the first club from the bottom tier of the Football League to reach Wembley in a major cup final.
