Steve Hadlow: Watching Chelsea loanees Mount & Tomori with interest playing for Derby. Impressed with defender Tomori has he loss weight or grown ? Next season for these 2?
Paul: Is Tom Lawrence usually this rubbish? 3 decent chances he's had to score and missed the target by a mile on all of them.

Tough crowd Lewis!
End-to-end stuff now as Nathan Redmond screws a shot over the bar. Who's taking penalties?

Am watching on BBC Sport App and it's exciting. The football not Brexit

This is woeful football. I think these two teams will battle it out in the championship next year. Hardly an advert for the Fa Cup? Bring back Le Tiss I say!

I expected Tom Lawrence to hit the target there. He's got time, he got the ball out of his feet, he just leant back and the ball got too far ahead of him.
He's getting into some great positions though. He really is.

Wow we've seen some missed chances tonight!
Derby are caught on a 4v2 counter, Oriol Romeu plays the ball at the right time to send Nathan Redmond in on goal but he can't beat Kelle Roos. Good save!

Tom Lawrence! No! Another chance for the Ram, tougher one this time but he lashes it well over from 18 yards.
Southampton send on Matt Targett for Kayne Ramsay.

That's a better chance than the one he had before. Tom Lawrence has made a difference but he's missed two great chances.

It's another great chance! Tom Lawrence again!
The Derby sub is a very good player but he's bobbins at headers. He's six yards out, between two centre-halves, he closes his eyes and bunts it over the bar. 50p head...

Rob Meech: So, do I continue watch two sides battling it out with seemingly no way of breaking the deadlock? Or do I watch the football? #SOTDER #BrexitChaos
Jon Mills: Southampton vs Derby County >> Brexit
Southampton 2-2 Derby
Right, Saints free-kick. Miles out. James Ward-Prowse has lined it up.
Over.

What a brilliant advert for FA Cup football. Great game and a fantastic second half. Massively enjoyed. Derby look dangerous. Their youngsters look outstanding. Tomori and Wilson standing out.

No comment Andy...
Derby make a fourth sub - they can in extra time of course - as Harry Wilson is replaced by Mason Bennett.

Andy Powell: Derby County knocking the Prime Minister onto BBC2 is the perfect metaphor for Britain right now.
Southampton 2-2 Derby
Sam Gallagher almost gets clear but that man Fikayo Tomori tracks it all the way.
Extra-time = a waste of time.

Matthew Scott: Theresa May to make emergency statement at 10pm condemning the pedantic use of VAR in Southampton vs. Derby. Strong leadership at last.
Luke Batty: Hope Hasenhuttl doesn't ever go walk his dog in #Southampton. The lad can't hold a lead to save his life.
Anthony: Fikayo Tomori has been absolutely brilliant in this tie.. assured in possession, bullish, strong and assertive in the air, another real prospect in Chelsea's youth.

The news is on BBC Two, that's 100% confirmed now.
I know it makes no difference really. It's one click of a button.
But you should see how people react when we move a game during Wimbledon...
