Neil Johnston and Gary Rose
Blackburn 0-0 Newcastle
Goalless at the break, but Martin Dubravka has been the busier of the two goalkeepers.
Bournemouth 0-0 Leicester
Still no goals in this one but Bournemouth have a chance as Philip Billing tries to pick out Antoine Semenyo at the near post, but the Leicester defence does its job just in time.
Jannik Vestergaard is then not far off turning a cross into his own goal.
Bournemouth edging closer.
Jordan Clark
Goal of the night!
Wow. Where did that come from?
Stefan Ortega is stunned as Jordan Clark's attempt from fully 25 yards finds the top corner following Ross Barkley's pass.
That was a beauty.
Luton 0-3 Man City
Pep Guardiola will be looking to make more changes to rest some legs with the tie all but in the bag.
Good luck trying to bring off Erling Haaland and Kevin de Bruyne.
They're having the time of their lives.
Blackburn 0-0 Newcastle
Sammie Szmodics is on to another great ball forward, he turns Fabian Schar inside out before hammering a shot on goal that Martin Dubravka tips over.
Blackburn 0-0 Newcastle
Better from Newcastle as Jacob Murphy chases a ball over the top. He is on to it but forced wide by the goalkeeper, before his cross is cleared.
Erling Haaland
HAT-TRICK!
Erling Haaland gets his third in the 40th minute after ANOTHER assist by Kevin de Bruyne.
It's Haaland's best finish of the night, dinking it over Tim Krul after being sent clear.
Manchester City are heading into the quarter-finals.

Total lack of creativity and commitment from Newcastle. Can’t wait for Howe’s Plan B…
Steve
Blackburn 0-0 Newcastle
Blackburn have had by far the better chances in this game as half-time approaches. Newcastle haven't really got going yet.
Luton 0-2 Man City
And that's the end of Jack Grealish's night!
Grealish looks distraught as his game is ended by injury.
The bad news for Luton is that Grealish has been replaced by Jeremy Doku.
Blackburn 0-0 Newcastle
Stephen Warnock
Former England and Liverpool defender on BBC Radio 5 Live
I really like Buckley, confident on the ball, very calm in the way he receives the ball. He's not the tallest but he can certainly put himself about, he's not afraid to tackle.
Bournemouth 0-0 Leicester
A strange one as Marcos Senesi sends a cross into the box but the bounce catches out Jakub Stolarczyk but, fortunately for the Leicester goalkeeper, the ball hits the post.
Luton 0-2 Man City
Is Jack Grealish carrying a knock? He's just been in deep discussion with the bench and it looks like City could be preparing a change. Grealish is carrying on for now.

Biting my nails watching Blackburn vs Newcastle. Hoping for a Sammie special at some point but this is a superb match so far!
Chelsea
Luton 0-2 Man City
Not bad from Cauley Woodrow who attempts an ambitious finish out wide from outside the box. For a moment that had Stefan Ortega worried.
Blackburn 0-0 Newcastle
Danny Murphy
Former Blackburn Rovers midfielder on BBC One
I think what we have seen here is that if anyone thought a Premier League side would turn up here and a struggling Championship side would roll over for them, that's certainly not the case.
Blackburn 0-0 Newcastle
Watch the moment as tennis balls were thrown onto the pitch in protest against the Blackburn owners.
Blackburn 0-0 Newcastle

I'm surprised Moran didn't hit it himself. He won it well and you just think he should hit it.
Dubravka does well. Important hand.
Blackburn 0-0 Newcastle
Stephen Warnock
Former England and Liverpool defender on BBC Radio 5 Live
The two best moves have come from pinching the ball off Newcastle. Moran waits perfectly to release the pass at just the right time, Dolan strikes it hard and low into the bottom corner. Dubravka saves a certain goal.
Blackburn 0-0 Newcastle
Almost for Blackburn as Tyrhys Dolan's decent strike is pushed away by Martin Dúbravka and agonisingly out of Sammie Szmodics' reach as he flies in at the far post.
