This would have been some goal as Alex Mighten runs from inside his own half to the edge of the Cardiff area but shoots straight at Dillon Phillips.

With just over 15 minutes to go a second goal for Forest would have surely sealed their passage to the fourth round.

I faced Wimbledon in the very early stages, just as they were coming through from the lower tiers and they were ready set in the system, the style that they became famous for. We came across them when they were totally unknown and honestly, what a shock to the system!

Now, I'm not saying Chorley are exactly the same but they ask a lot of the same questions - and it is just extremely hard to play against.

You must get the ball down, you do not take them on at their game. What you do is fight your battles but put your game on top of that. That's what Derby are trying to do.

Not bad options for Norwich to introduce from the bench.

Teemu Pukki and Emi Buendia are on for the final 20 minutes, in place of goalscorer Jordan Hugill and Todd Cantwell.

There won't be any goal for Maxime Biamou despite his five attempts, as he and Ben Sheaf make way for Amadou Bakayoko and Matty James.

Nottingham Forest are really struggling to create anything in this half as Cardiff continue to look the most likely to score. This time Joe Ralls tries his luck from distance but Jordan Smith is behind it all then way

Big chance for a Luton second as Danny Hylton pokes the ball through for Elliot Lee, but he can't get any contact on the ball to steer it goalwards.

Chorley look dangerous on the break and Elliot Newby chases a ball from midfield, cuts inside before bending an awkward shot at Matt Yates in the Derby goal.

Ancelotti continues to twist, sending on Gylfi Sigurdsson and Yerry Mina for Lucas Digne and Tom Davies.

The home side are not really testing Jamal Blackman.

Interesting to see Bobby Duncan up front for Derby County, he has held the ball up a couple of times now, which he wasn't allowed to do in the first half.

He was really getting roughed up a bit. It doesn't matter if they players you are playing against are physical, taller, older - you need to be able to hold the ball up.

Well done him. That could be key for Derby getting a foothold back in this game.

Derby are a different side in this half. They are showing much more intensity and getting forward in numbers.

This is a testing period for Chorley and one of those fans watching over their garden fence is rapidly and nervously chomping on a chocolate mousse.

I'm learning words I didn't even know existed listening to this match. The technical areas are 'lively' to say the least.

Boreham Wood continue to make a good game of this and Millwall boss Gary Rowett has responded with two changes.

Jon Dadi Bodvarsson and Tom Bradshaw are on for Tyler Burey and goalscorer Kenneth Zohore.

Cardiff continue to come forward in search of an equaliser as a clearing header falls to Will Vaulks 30 yards from goal, the Cardiff man shoots first time but it is straight at Jordan Smith.

Huge chance for Reading to be level. The ball is crossed from the right and falls to Sone Aluko. He has just the keeper to beat but smashes his effort against the bar and over.

Maxime Biamou again!

And once again, 20-year-old Norwich goalkeeper Daniel Barden is there to save Norwich.

Biamou has had several good chances now, but it will be beginning to feel as though there's just no way past Barden today.

Carlo Ancelotti has seen enough. On come Bernard and Abdoulaye Doucoure to try and inject some urgency into the home side. Alex Iwobi and Anthony Gordon make way.

Ben: All those saying that Derby playing their youngsters when they have no choice devalues the competition are absolutely right. But don't forget the less prestigious EFL Trophy where there are some Championship sides playing their u23s. Is that competition devalued too? Also the wage bill for Derby's team of youngsters is likely to be larger than Chorley's wage bill.

Chorley come charging out of the blocks as Matt Yates produces a superb save, getting down quickly to keep out Connor Hall's strong effort that was heading towards the bottom corner.

Maxime Biamou continues to cause Norwich plenty of problems.

The Frenchman does well to send a ball in from the left, but he's only got a couple of team-mates up in support and Norwich are able to clear.

Ryan Giles then fires over from distance. Coventry have been much better in this second half.
