Famara Diedhiou has scored in three of his last four FA Cup appearances for Bristol City, netting in both the third and fourth rounds so far this term.

Will he be the hero at Bramall Lane? Bristol City haven't reached the quarter-finals since 1974.

He starts tonight.

The expectations on Manchester CIty will go through the roof now. It was a predictable night - Swansea have given it a go but Man City have just had too much class and too much quality.

Sheffield United have already beaten one Bristol side - Rovers - in the third round and this is their chance to do the double.

I think the Blades will do it too. Bristol City's form has dipped a bit in the Championship of late, and they have fallen away from the play-off places.

Prediction: 2-0

The red button and online coverage of this one is just starting - press play on the relevant bit at the top of the page.

Manchester City join neighbours Manchester United and Bournemouth in the quarter-finals.

Two additional minutes.

This has been a thoroughly professional performance by Pep Guardiola's side. It's going to take something special to stop this run they are on. They're spraying the ball around with a spring in their step in the 90th minute.

What about the Champions League, Callum?

Unless you're a City fan of course...

A lovely turn of speed from Tommy Doyle who gets away from his man after being released by Gabriel Jesus but he drills it wide.

Phil Foden, unmarked and waiting for the pass to tap home, is not impressed.

Matt: Where has that been all game. A fantastically well-worked goal from Swansea. If they'd played like that from the start, this scoreline would be different.

Another goal would make things interesting.

Manchester City, though, have been stung by Morgan Whittaker and are threatening to increase their lead.

Steve Cooper looked like a proud dad when that goal went in. The Swans boss was beaming and clapping his hands. That was some finish by Morgan Whittaker.

This is what you call clinical!

Kieran C: Steffan’s feet must be absolutely freezing

Steve Olive: Not sure if it's raining in Swansea but the floodgates just opened.

Azrael: City are unstoppable on this form.

Claudio Gomes, the owner of Manchester City's No 81 shirt, is on for Rodri.

Rodri has put in another cracking shift.

He's down on the floor after taking a knock and his game could be over.

He's been involved in two of his side's three goals.

With this tie already over barring something miraculous, Swansea boss Steve Cooper is thinking ahead of a Championship trip to Sheffield Wednesday this weekend.

He has just made a quadruple substitution, with four players who can expect to be involved at Hillsborough given some rest.

Manchester City have also made a change, with man-of-the-moment Phil Foden on for Bernardo Silva.

Having embraced his former England Under-17 player before kick-off, Cooper will be hoping Foden does not make the scoreline any uglier - from Swansea's point of view - in the last 20 minutes.

When did you see a team make FOUR changes at once?

Swansea have just made a load of substitutions.

Paul Arriola, Morgan Whittaker, Jake Bidwell and Kieron Freeman are on.

Off go Jamal Lowe, Jordan Morris, Marc Guehi and Connor Roberts.
