Clarke Oduor weaves into the area but sees his goalbound effort well saved by Louie Moulden who has been hugely impressive for Moors this evening too.

Cambridge United have never lost at home in an FA Cup replay. They have won 10 and drawn two – though they did lose on penalties after one of those draws, against Macclesfield in 2003.

Will spot-kicks be the decider tonight?

Derby boss Paul Warne tells BBC Three:

"The older lads marshalled the team through the game.

"I want to see a consistency to our game that I'm not sure I saw. We were a bit too open for my liking.

"It got some minutes into the younger lads and overall I'm pleased to get through basically injury free.

"We played Liverpool last week (in the EFL Cup) and we were the underdogs. There are no teams you will play against who will just lay there and have their bellies tickled."

We're reached half-time in extra time in both our remaining FA Cup first-round replays.

Non-league Curzon Ashton and Solihull Moors have done so well to hold EFL opposition over a total of 195 minutes - can they get their reward?

We have 15 more minutes to find a winner, otherwise it's penalties!

Ben Killip was a large part of the reason Hartlepool are not already in the changing room and the keeper has produced another fine save to turn a header from Ben Coker over the bar.

Reghan Tumilty was the one who ensured extra-time with a last-gasp equaliser for Pools and he's almost put the hosts ahead with a long-range effort which flies into the side-netting.

Derby skipper Richard Stearman tells BBC Three:

"They gave us a great game in the last tie and probably deserved this replay.

"I think the attacking boys really enjoyed themselves and I was pleased to keep the clean sheet.

"I'm delighted for Lewis Dobbin because he has come here on loan and worked really hard. He's a great young lad.

"Part of my job is to mentor the young lads here. I think the future is bright.

"The gaffer's great. I don't know if you've spoken to him but it's constantly like he's had 10 coffees."

Cambridge continue to press but this time it's Joe Ironisde who can't find the target with a header from a Paul Digby cross.

I've absolutely loved it tonight.

It's been a great atmosphere.

Jack Lankester sees a shot deflect onto the roof of the net for the hosts.

Extra time is just what Cambridge did not want and they don't have an attacking sub on the bench.

The positive side is Torquay have kept going, they've never dropped their heads.

Their shape in the second half was better than the first half.

The difference between the two teams was the quality around the penalty area.

Josh Hancock does well on the edge of the box for The Nash but his drive is saved my Cambridge keeper Will Mannion.

Two minutes into extra-time David Ferguson works his way into the area but fizzed a shot narrowly over the Solihull bar. There have been chances at both ends in this one, with keepers on top so far.

Job well done by the League One side.

A Mark Ellis own goal plus strikes from Will Osula and Liam Thompson basically had this done and dusted before the break.

Lewis Dobbin cracked home a superb volley to make it 4-0 and David McGoldrick wrapped it up with a neat finish.

The National League strugglers were game all evening, and had some opportunities to get back in it at 2-0 down, but they were ultimately blown away by ruthless finishing from the Rams.

It's back to the battle to avoid relegation to the sixth tier for them now.

Just not Torquay's night.

Aaron Jarvis bears down on goal after a slip in the Rams midfield leaves him with a run on goal but Joe Wildsmith in the home goal wants his clean sheet and he gets down well to deny his powerful strike.

The 100-minute mark is up.

If you're wondering why there's so much time added on then one of the reasons is one of the assistant referees pulled a muscle and you would be really surprised at how fiddly it is for the fourth official to take over all the equipment to take over linesman duties.

Two minutes to go now.

We're under way in extra time in two FA Cup first-round replays.

Can non-league Curzon Ashton and Solihull Moors dump out an EFL side here?
