Brentford 0-1 Leicester

James Justin wins an aerial duel with Halil Dervisoglu but lands awkwardly. Painful one! He should be fine though.

In these situations you have got to go for the far post. Not the best option there from Demarai Gray.

It really was a beautiful pass from Dennis Praet! Even KDB would have been proud of that.

Veet Voojagig: Oh that Leicester goal is a thing of pure beauty.

Gareth Hancock: The commentators didn't give that Praet pass for the Leicester enough credit. It was a thing of beauty.

Craig Smith: If KDB made that Praet pass...

Demarai Gray tries to catch Luke Daniels out at his near post with a low, driven effort from the free-kick.

It fizzes into the side-netting.

Leicester are running rings at the moment.

Ayoze Perez beats Dru Yearwood on the left and wins a free-kick JUST outside the box. Brentford are struggling.

It's a brilliant goal this from Leicester. Brilliantly worked. The patience they have on the ball in midfield between Choudhary and Praet - they move it across with patience and they have just waited for the right time. Thompson just switches off at left-back and the ball splits them apart then it is all about can he pick out Iheanacho at the back post. I don't think there was any doubt when he got in this position that he was going to stick it in the back of the net.

Marc Albrighton's cross is headed to the edge of the box. Hamza Choudhury follows it up but his shot is blocked.

Another ball from the left is played into the six-yard box but is behind Demarai Gray. It comes to Dennis Praet on the edge and he thumps one into the back of a defender!

Kelechi Iheanacho has scored nine goals in nine FA Cup starts (five for Leicester and four for Man City).

Fantastic goal there. It's Premier League quality, isnt it? It's a perfect ball to the corner, nothing Brentford could do about it. Nightmare start for them but what a great start by every Leicester player.

The one thing noticeable with teams at the Premier League level is they're just that bit quicker. The forwards are lightning quick. Iheanacho will hammer both the centre-backs for pace every time the ball is put over the top.

That is a goal-saving tackle by Racic, unbelievable! Get that wrong and it's a penalty, a possible sending off, a nightmare situation but he made the perfect tackle there. Leicester have started really well, a nice high tempo. They're playing a very attack-minded team.

Heavy touch from Danny Ward, who then pulls out the tricks to get past Halil Dervisoglu and is then fouled. Nice!

Wow!! It's nearly 1-0 to Leicester within 20 seconds.

Kelechi Iheanacho slips it through to Ayoze Perez, who rounds the keeper but can't quite get the shot away before he's tackled by Luka Racic.

Brilliant defending but that was very easy for Leicester!

With the way Leicester have picked up recently you would think they would come here with confidence. He's picked a strong side even though they have made some changes, but with the names on that team sheet you would feel that Leicester do have enough.

It will be a good game. There are a lot of players going out to try and impress, they know the nation's media have their eyes on this little patch of green grass in West London. They'll be up for it and both teams will want to attack. Tight little ground, brilliant atmosphere, this is everything you want in an FA Cup tie.

Off we go! Who will join Sheffield Wednesday in the fifth round?

FEAST.

Birmingham are playing 'away' at their own stadium against Coventry. Yes, you heard that right. The Sky Blues are groundsharing with Blues this season and the League One club are the designated home side.

That means Birmingham's players are in the away dressing room and their fans are in the away end of the ground.

To mark the bizarre occasion of playing 'away' in their own stadium, Birmingham have produced limited edition souvenir half and half scarves decked out in each teams colours featuring the FA Cup.

While there have been some takers, other Blues fans reckon their side had scored a marketing own goal with the item.

"A Jack Grealish scarf would have been more popular," said @Greekbluenose on Twitter in reference to the captain of Birmingham's arch rivals Aston Villa.

Fellow Birmingham fan Emily Drakeley told me: "Birmingham fans don't do half and half scarves. That's not our vibe."

Here come the teams! Brendan gives a wave to the visiting fans. Brentford's supporters are LOUD.
