Tom Cleverley would love a goal against Liverpool but he cannot shape for a shot and gets crowded out. Villa have a corner which is well dealt with but make no mistake, they look more likely as things stand. A slight concern here though is Nathan Baker struggling after an aerial challenge. He looks weak, despite the big burly beard. A change looks afoot...

"This game is an intriguing one. Already Aston Villa have demonstrated their ability on the break if Liverpool are going to come at them, but I think Villa are now overplaying if anything. They should be looking for Christian Benteke earlier. For Liverpool, Raheem Sterling has already put Villa under a bit of pressure."

Steven Gerrard has built a career with quick thinking and sharp passing, this time his mind is operating too quickly for his feet and his ball into the channel finds no one. Undeterred, his side recover possession and the skipper feeds Raheem Sterling, a departing generation to the new one, Sterling drives into the area but is held up and Villa will have a goal kick.

Aston Villa are shading possession with around 55% as we speak, they'd have taken that before kick-off. The game does not have a terrific flow by any means but of the two, Villa look more fluid. Christian Benteke tries another showboat flick but this time gets it wrong. Tim Sherwood seems to have injected confidence aplenty into his talisman.

Teenage midfielder Jack Grealish is already a firm favourite among Aston Villa supporters and today he is hoping to impress them further with a starring role in a huge FA Cup tie - just like one of his ancestors did 110 years ago.

That's because the 19-year-old's great-great-grandfather Billy Garraty was named as the man of the match when Villa beat Newcastle in the 1905 FA Cup final.

"There is a picture of that winning side hung up at the Grealish home, with his great-great-grandfather stood in the middle," says BBC Radio 5 live commentator John Murray. "What more inspiration for a young Aston Villa fan? It is all there for him."

"Good Aston Villa start. Christian Benteke is trying to get himself isolated in the air against Emre Can as opposed to the stronger Martin Skrtel while Villa youngster Jack Grealish has made a very confident opening, demanding the ball at every opportunity."

This is a good spell for the underdogs on semi-final Sunday. A prolonged spell of possession, each pass confidently struck. Finally Liverpool regain some ball and Raheem Sterling is giving chase to a ball into the channel but Ron Vlaar matches him for every yard. Quiet start from Sterling so far.

"Every time the ball goes into Benteke, he knows where everyone around him is, he's playing with confidence. It was a beautiful flick from the Belgian inside to N'Zogbia. N'Zogbia does well to get the ball out of his feet and it is a fantastic shot."

Pick the bones out of this. Where will the errors come? Where are the weak points. A slight contrast in styles as Liverpool pass, pass, pass but Villa want to get down to it more directly and Benteke beautifully flicks into the path of N'Zogbia... over the bar from 25 yards with a tip from Simon Mignolet.

"Aston Villa need to sort out picking up the runs of Philippe Coutinho. A few moments ago he ran from deep through the middle and then he pulls out on the left with no Villa player in sight of him.

"Liverpool have started the game marginally better - it was a scrappy start with a few nerves out there. Villa have done OK - they have been pretty steady defensively apart from those Coutinho runs."

A neat Villa interchange down the right flank and Ashley Westwood switches play nicely but Christian Benteke cannot pick out a cross. The attack re-builds though and the big striker cleverly brings Jack Grealish into play. No fear again from the youngster who forces a corner. It's short, can they work a delivery? Yes... too high. Tim Sherwood is not happy with that.

"And it's Aston Villa, Aston Villa FC..." sings one half of the ground. Could they be silenced here though? Philippe Coutinho is in fine form and drives at the full-back before cutting back for Joe Allen who shoots wide from 20 yards. Allen got his first Anfield goal on Monday. No such threat at Wembley.

"Aston Villa look to have settled nicely. Before Tim Sherwood came here there was a lack of spark and ambition about Villa. You can't say that any more. They move the ball so much quicker now and they are full of confidence. Today they will look to get the ball up to Christian Benteke, who is so strong up front. Gabriel Agbonlahor is a big miss though. Those two have combined really well."

Now it's the turn of Tim Sherwood's side to roll the ball about under little pressure. It goes back to Shay Given... thump upfield. Kieran Richardson may not have too much love for Liverpool having started his career at Manchester United. He fouls Lazar Markovic but a free-kick delivery is headed away.

Dejan Lovren, Martin Skrtel, Alberto Moreno, they all get an early touch and the latter is flattened by Charles N'Zogbia near his own area to give us our first foul. A percentage start all round. Jack Grealish is in midfield for Villa, a local lad and at just 19 shows no fear as he tries to commit a foul early on. He succeeds, naughty, naughty Emre Can.

And here we go. Liverpool attack the Villa end, the underdogs will get to face their own fans in the second period. Possession is king early for the Reds.

Osbert Moor: Martin Skrtel coming back is huge. Liverpool's only defender who'll be able to meet Christian Benteke's physicality. They'd struggle without him.

Luke Tandy: Very surprised to see Jack Grealish starting ahead of Scott Sinclair but I hope to be proved wrong!

If Steven Gerrard was a poker player, his face would scream nothing but 'focus.' He stands dead-eyed in the tunnel. A look up to the ceiling, then a glare into the distance. You could launch a rocket next to him and he would know little about it.

The dramatic music rings around Wembley, the fans know the players are coming, it's tense, tangibly so, and here come the players.

"This is a bit of a bonus for Aston Villa to be coming to a semi-final. There's always a slight amount of pressure, but we're certainly the underdogs. Liverpool are by far the favourites today. It's great going into games when you're the underdog.

"In midfield we'll see a direct conformation between Fabian Delph and Jordan Henderson. Delph has had a lot of pressure put on him as captain, but he lets his feet do the talking. It will also be interesting to see how Jack Grealish deals with it. When he's been given the opportunity, he's excelled, and this is the kind of stage I'd expect him to enjoy."
