Now Jack Grealish wins a foul from opposite number James Maddison. Villa Park is bouncing.

It's the perfect counter goal - sitting deep and hitting Leicester on the break.
It's a great run by Matt Targett and what a strike. Maybe Kasper Schmeichel should do better but Villa won't care about that.
They're 1-0 up against the run of play.
Matt Targett
Villa take the lead! It's excellent hold-up play by Jack Grealish and he then flicks it into the path of the flying Matt Targett.
Targett hits the, um, target with a nice bouncing shot from a tightish angle which Kasper Schmeichel can't do anything about.
Villa do get out...
Aston Villa 0-0 Leicester (1-1 agg)
Villa just can't get out at the moment. Every time they win the ball and threaten to come away with it, Leicester get it back and keep the pressure on.
This time Ayoze Perez has a shot blocked.

Aston Villa manager Dean Smith is looking to become the first Englishman to reach a League Cup final since Bradford City’s Phil Parkinson in 2012-13.
The last English person to do it with a Premier League club was Harry Redknapp with Spurs in 2008-09.

It's James Maddison v Orjan Nyland. Excellent footwork from the Leicester City playmaker to get a bit of space and then his shot from outside the box is tipped around the post by the Villa back-up keeper.

Jamie Vardy may be missing from Leicester City's starting line up but the Foxes are looking very dangerous with the pace of Kelechi Iheanacho and the threat of James Maddison.
Villa need to settle down a bit here but Leicester's speed will provide a real test.

A league cup is a trophy. Qualifying for the champions league is not a trophy. Ergo objectively the league cup is better than CL. You play footy to win trophies. Here endeth the sermon

As a Birmingham fan I'm praying for a Leicester win because our League Cup in 2011 is about the only thing we have over the Villa!

Aston Villa are being a little too adventurous. They need to play deeper and get more bodies behind the ball.
If they're going to make it an open game, I think Leicester are going to win it.
Aston Villa 0-0 Leicester (1-1 agg)
Leicester have had three good chances in seven minutes. Ayoze Perez can't quite control the ball in the box, it breaks to James Maddison 20 yards out but he drills his half-volley wide.
Aston Villa 0-0 Leicester (1-1 agg)
An excellent end-to-end start. Already had more action than some entire games I've watched.
Aston Villa 0-0 Leicester (1-1 agg)
Leicester's second shot on target. It's an excellent strong hand by Orjan Nyland to tip James Maddison's low 16-yard shot around the post.
Aston Villa 0-0 Leicester (1-1 agg)
An amazing run from Matt Targett, who runs the ball out of defence, plays a one-two with Douglas Luiz and then another with Jack Grealish, before having a low shot-cross blocked by Kasper Schmeichel.

A great start, it's very lively and there are a lot of nerves around.
Tyrone Mings must put the ball out there. It's early in the game, you don't want to take any risks.
Aston Villa 0-0 Leicester (1-1 agg)
Leicester striker Kelechi Iheanacho has been involved in seven goals in his last four appearances against Aston Villa (five goals, two assists), including scoring as a substitute in the first leg.
Aston Villa 0-0 Leicester (1-1 agg)
Early chance for Leicester City. Tyone Mings isn't strong enough as Kelechi Iheanacho barges past him. Mings has arms on the Foxes striker who stays on his feet and blasts the ball straight at Orjan Nyland.
Aston Villa 0-0 Leicester (1-1 agg)
Leicester are unbeaten in their last 16 away League Cup matches - although lost two of those on penalties.
Aston Villa 0-0 Leicester (1-1 agg)
Good news for those of you who have an early bedtime tonight - there won't be extra time.
If this game finishes level - with any scoreline because there is no away goals rule in force - we go straight to penalties.
