FT: Two Connolly goals see Brighton beat Swansea
Kelechi Iheanacho
Done and dusted. And it emphatic fashion.
Kelechi Iheanacho beats his man, takes a look up and absolutely lashes a rising shot into the roof of the net from the edge of the box.
What a way to seal the tie.
Chelsea 1-1 Aston Villa
Romelu Lukaku is on for Chelsea as they try to get the job done within the 90 minutes. He looks like he is through but a superb tackle from Kortney Hause denies him. Brilliant defending.
Man Utd 0-1 West Ham
West Ham are being penned back and Mason Greenwood screws wide with the ball landing in the Old Trafford tunnel.
Man Utd 0-1 West Ham
A big stop from Alphonse Areola, smothering Anthony Martial's shot after the ball dropped into his path via Jadon Sancho's deflected curler.
Man Utd 0-1 West Ham
He's off the bench and nearly makes an impact, but Bruno Fernandes pulls his shot wide from 25 yards out.
Not the same outcome as in the Newcastle game.
Eddie Nketiah
Oh, what a finish!
Eddie Nketiah pulls out a little inside of the foot flick to polish off a lovely move. Bukayo Saka is involved, with Cedric Soares providing the low cross.
That is class.

BBC Sport at Old Trafford
Manchester United have gone for it.
Ole Gunnar Solskjaer is basically playing with a back three now, with Anthony Elanga pushing wide in a wing-back role.
West Ham will try and soak up the pressure and hit on the counter.
A fascinating end to the game looming.
It's all over at the Amex Stadium.
Brighton are safely through thanks to Aaron Connolly's first-half double.
Swansea will rue a number of missed chances.
Emile Smith Rowe
Game over.
AFC Wimbledon's brave challenge is over as Emile Smith Rowe slots in from close range. The away side just couldn't get it clear, allowing the Gunners to feed the ball in from the right for the neat side-foot killer blow.
Brighton 2-0 Swansea City
Brighton almost add a third goal in stoppage time as Pascal Gross drills a free-kick onto the crossbar.
Man Utd 0-1 West Ham
Here he comes.
Bruno Fernandes has been summoned and will get 18 minutes, as weill Anthony Elanga.
Jesse Lingard and Alex Telles make way.
Chelsea 1-1 Aston Villa
Oh, how has he missed?!
Ruben Loftus-Cheek's ludicrous little backheel sets up Mason Mount but he somehow pulls his shot across goal and wide of the far post.
Man Utd 0-1 West Ham
Double change for West Ham.
Pablo Fornals and Nikola Vlasic replace Manuel Lanzini and Arthur Masuaku.
Wolves 2-2 Tottenham
Great save, John Ruddy!
Harry Kane is in space, just a few yards out and meets a cross with his head, but the home keeper shows quick reflexes to block.
Cracking game.
Chelsea 1-1 Aston Villa
This is a different tie now!
Anwar El-Ghazi is slipped in down the left but he fires his shot straight at Kepa.
Man Utd 0-1 West Ham
Bruno Fernandes is sitting on the bench, chuntering away and flapping his arms around with Tom Heaton and Anthony Elanga listening in.
Will he get the call?
Man Utd 0-1 West Ham
West Ham goalkeeper Alphonse Areola is being kept busy now.
Jesse Lingard swings a left boot at the ball from the edge of the area but it drifts straight at the Hammers stopper.
Cameron Archer
Young striker to the rescue!
Matty Cash's cross from deep on the right is a superb one, but the header from Cameron Archer is even better. He meets it and steers the ball into the top corner. No saving that. Boy did he enjoy it.
Game firmly back on!
Man Utd 0-1 West Ham
What an impact this would have been from Mason Greenwood, drifting in behind and taking Donny van de Beek's pass, but he snatches at it and scuffs the shot straight at Alphonse Areola.
Man Utd 0-1 West Ham
Here's the change, young man on for the elder statesman.
Mason Greenwood replaces Juan Mata.
