Away we go...

Michael Reilly: Just saying - Harry Winks is a star of the future for club and England. Ignore the hype over others and watch.

Laurent Koscielny is coming on at the break. He replaces Henrikh Mkhitaryan. RESHUFFLE.

Back up and running very quickly at Chelsea...

Spurs haven't won at the Emirates since 2010. This would be a big one in more ways than one.

As the game wore on Bournemouth got more and more into it. Initially it felt like a matter of time until Chelsea scored. When Bournemouth go forward and get it into the front two early, they look dangerous. But they look vulnerable to counter-attacks.

I think Bournemouth will go in happy and Chelsea a bit frustrated they're not ahead.

Absolutely, categorically not.

Sian Massey-Ellis might not be building up too much of a sweat as the assistant VAR, external official for tonight's quarter-final between Arsenal and Tottenham, but here's an insight into the training for the country's top-level referees...

You'll be able to read more from Sian about what she loves about being a referee on the Get Inspired index on Friday.

That's the difference. Spurs have taken their chances, Arsenal have created a fair few. On reflection, I think Spurs have just nicked it with their quality in the final third.

If you don't take your chances, you will come a cropper. If I've got to put my mortgage on who will score on a one-on-one, it will be Son over Henrikh Mkhitaryan.

If it stays like this, Spurs would join Burton and Manchester City in the semi-finals.

Chelsea v Bournemouth would go to penalties.

Matteo Guendouzi is in the book for an absolute old-school hack on Lucas Moura. Have some of that.

A very decent 0-0.

Unai Emery likes this. Sokratis rises high to meet a corner but his header is just wide. Danny Rose was on the post. Not sure he had it covered...

Oh my word. Arsenal have had so many good chances. They should have scored. I don't know what the keeper is doing. Don't take any risks. Ramsey should have turned and struck he ball, don't do anything too fancy.

Not for the first time, Spurs' stand-in defenders fall apart! Paulo Gazaniga has a clearance charged down by Pierre-Emerick Aubameyang after he got a bad backpass, Ben Davies then makes a hash of his clearance and it's almost a tap in for Aaron Ramsey.

Gazzaniga then makes a brilliant save to turn another Ramsey effort on to the post!

Keith Binfield: Has someone forgotten to tell the teams this is the Carabao Cup? Didn't expect such a blood and thunder cup tie

Clevedon Town Under-18s - who pay to play - remain 2-0 down at home to Man City's young stars in the FA Youth Cup, with an hour gone.

We gather there are scouts here from clubs including Man Utd and Bristol City - as well as around 1,500 fans. Quite a night for these students who usually play in front of 50 people.

Here are the teamsheets... With a few names in the City team that you may well recognise in a few years, including England U17 midfielder Tommy Doyle, who has been absolutely everywhere tonight.

Whatever the game, whatever the competition, Willian is a constant for Chelsea. He never seems to get the night off.

He's been as lively as ever tonight as he has a shot well blocked away.

You leave Grzegorz Rasiak alone! As a young(er) journalist it took me months to be able to spell his first name without looking.

I hope that's right after I just said that...
