The hour ticks up and Liverpool have questions to answer. Mario Balotelli will be thankful the offside flag just rendered his missed header meaningless. They have Rickie Lambert on the bench or the energy of Fabio Borini.

One thing is for sure, Jack Grealish is going to get some good column inches in the morning. He only made his first Premier League start 12 days ago in the 3-3 draw with Queens Park Rangers. He looks like he's been playing for 10 years.

"That was just all round brilliant play by Aston Villa. Jack Grealish shows maturity well beyond his years to set up Fabian Delph. Most young players would shoot rashly from there - but he keeps his composure to pick out Delph with a beautiful ball."

"It's the same three players involved in the first goal. Composure from Jack Grealish, a great finish from Fabian Delph and good running from Christian Benteke. It's far too easy from a Liverpool point of view. Will Brendan Rodgers now want to change things again?"

A wonderful Aston Villa goal and Fabian Delph has now scored one and made one in this game. His right-footed finish from 10 yards is only part of the story. Jack Grealish was at the heart of the build-up, receiving a Christian Benteke backheel to play the ball into Delph's path and he opened up onto his right peg and drilled it past Simon Mignolet.

What have you got Liverpool? Wembley is claret, blue and noisy.

Brendan Rodgers has been praised for changing Liverpool's shape in games this season and he does so again to include Mario Balotelli. It looks unorthodox with the Italian through the middle on his own with a five-man midfield behind him - Philippe Coutinho and Raheem Sterling advanced from Steven Gerrard , Joe Allen and Jordan Henderson.

It's at the other end where immediate threat looms though as Christian Benteke has a shooting chance, deflected into the hands of Simon Mignolet.

The goalscorer Philippe Coutinho has been picking the ball up on the left of the Villa area all day, here he is again, he rolls it back to Steven Gerrard. A highlight reel moment coming up? Nope. One more for the bloopers as Gerrard shoots high and wide, much to the amusement of Villa fans at the other end.

Ken Gorry: It's said that Gerrard once carried Liverpool, now Liverpool carrying him. He has to contribute more.

MJC1973: Miracle seeing Rodgers change tactics mid half but not helped by the captain being invisible most of it. Play very disjointed. Credit to Villa. Much different side to one we beat 2-0 a few months back. Benteke back to scary best.

"Balotelli coming on? Well, Liverpool needed something because they weren't getting enough possession to supply Sterling. So it gives them more of a presence up front. But it depends which Mario Balotelli turns up - that's the gamble that Brendan Rodgers has had to take.

"The other change made by Rodgers is taking Steven Gerrard out of that attacking midfield position and put him back into a more holding role. That's where he needs to be - so he can control the game."

Jack Grealish, socks around his ankles almost, ducks and weaves with the ball to tee up Charles N'Zogbia. He has options but will look to shoot left-footed from 20 yards... over.

When the Villa beat Manchester United 2-1 at Wembley in 1957 they became the FA Cup's most decorated team with seven wins. But it says much for Villa's recent history that their last success in the competition calls for black an white pictures.

But in the passing 58 years, a time span which has witnessed 10 Prime Ministers, five recessions and 22 different managerial spells at Villa Park, the club have contested just one final - the 1-0 defeat to Chelsea in 2001.

No time like the present to move towards righting the wrongs...

An early sprint to close down from Mario Balotelli. Can he give his side a focal point up top like Christian Benteke has at the other end?

The Reds do bring on their controversial Italian. Lazar Markovic is hooked. Whether that is a fitness or performance issue is unknown. On trots Balotelli. His shorts are long, he smiles to the fourth official.

We are monitoring the teams closely. Mario Balotelli was warming up at half time. His introduction could be interesting.

No changes for Villa, for Liverpool...

Warning. This post contains material which does not wax lyrical about Philippe Coutinho as everyone seems to recently.

Despite finding the first goal of the day, the Brazilian has been Liverpool's most wasteful player, completing just 71% of his passes.

Jack Grealish - and I don't use this term lightly - has been superb for Aston Villa. He's made 33 passes, 97% have found feet

James, London: A Lambert team would have caved at 1-0. Great fight from Villa.

Brentwr: Gerrard is a passenger. A season too far.

Zahed: Benteke, super player. Finally over his injury.

Good luck calling the winner here. This is tight and the stats show it. Even possession wise, close in terms of territory with Villa slightly shading things. Extra time and penalties anyone?

"Aston Villa manager Tim Sherwood will be the happier manager after that first half. Not only do Villa look the more relaxed side but they showed the character to respond quickly to going behind. Christian Benteke is proving hard for Liverpool to handle and youngster Jack Grealish is playing in a relaxed, composed world of his his own."

"I've watched a lot of Villa and Benteke was not getting the service before Tim Sherwood arrived. So I think the thing which Sherwood has done is to get everyone around Benteke playing better and has built their confidence up. Now Benteke is getting the service and taking the chances."

All of the talk before kick-off was Steven Gerrard. Christian Benteke was an extra, the Trigger to Gerrard's Del Boy, but he looks every bit the lead man.

Liverpool will kick themselves for throwing away a lead which would have made half-time dialogue far more pleasurable but Villa deserve at least what they have. They look unperturbed by the underdog card.
