Will Hughes has been absolutely outstanding. He's controlled the game. He's going to be a big miss for Derby.
It looks like Derby are getting a bit tired. They have to stay compact. There are more goals in this game.

That is a shame. Will Hughes has shown some really nice touches of quality this evening. That is not a change Steve McClaren will have wanted to make.
Derby County 2-1 Leicester City
Will Hughes, linked with a move to the Premier League for as long as Juan Roman Riquelme, is having to come off. On comes Jacob Butterfield.
Leicester send on Riyad Mahrez. BIG.
Shinji Okazaki comes off.

Jamie Vardy looks just as sharp as always but Leicester are just not creating the chances for him. When you look at his body language, he doesn't look any different to last season.

Bad news brewing for Derby perhaps. Will Hughes has just hobbled away from a challenge, could be a dead leg, could be something more. Frowns all around.

'Zombie Nation' doing the rounds in the ground now. Classic stuff.
Claudio Ranieri is deep in thought on the sidelines, his side have been much better since half-time.

It was a fabulous ball from the right-hand side. Everybody this side of the stadium thought it was in the back of the net. Big chance in the game.

And now it's Derby's turn to miss a great chance! What a ball in from the right from Chris Baird, in the corridor between keeper and centre-backs, nobody in a Leicester shirt wants to attack it and it skips on in the rain. Johnny Russell is waiting, beyond the far post, and he heads it powerfully into the side-netting.
Great chance.

It is a poor strike on the free-kick from Gray. He didn't catch it and it was never threatening to go over the wall.
There is an urgency about Leicester to try and reassert themselves in the game. Derby need to get out and play in Leicester territory.

Proper penalty-box pinball stuff.

Awful free-kick. Demarai Gray has a seven-man wall to contend with and he punts it ankle-high into it.
Derby County 2-1 Leicester City
Demarai Gray is a nightmare for defences. Jamie Vardy wins a header and the former Birmingham winger flies through a gap, chopped down by Alex Pearce who goes into the book.
Free-kick in a very good area here. Just outside the box.

Okazaki is working just a little bit deeper and it is having a good effect. Vardy is staying up to occupy the Derby defence.

Niche stuff Rob, but I like it.
I think this is comfortably the best Friday-night game I've done all season. My memory is woeful though so that might not be saying much.
Leicester have started the second half like a top Premier League team after all. Surely they can find a leveller if they keep this up?

Robert Hardie: Craig Bryson is nicest pro footballer I have ever met. After Bob Wilson, obviously. Great to see him score. Bryson, not Wilson.

Great football from Leicester. Carson dived for the first shot and was still down when Okazaki's follow-up came in. If the shot had gone anywhere else it would have been a goal.

It looks like Leicester used all their good luck up with that Darren Bent own goal in the first half.

Not as big a chance as that though! Leicester are somehow still behind and sub Demarai Gray has made the difference. He is played into space and bends a low shot against the base of the post, Shinji Okazaki is on to the rebound but sees one shot blocked and then a second saved by Scott Carson, while on the floor again! Remarkable.
