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!!"
It's almost time to get underway - enjoy the game!
Villa Park is rocking tonight as the teams come out, with 6,500 Bradford fans having made the trip.
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.
Not many of you backing the Bantams to see the upset through. Anyone think they'll do it?
Jon Crutchley - "Don't ya wish your striker was benteke!"
@_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."
There's plenty of feedback coming in from both sides. Here's what you've had to say...
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.
Refereeing tonight's encounter is Phil Dowd (Staffordshire).
Right, without further ado, here's some team news for you...
The teams are in and I'll be winging them your way in just a second but beforehand why not get in touch with your thoughts on the match?
