Former Blackburn Rovers midfielder on BBC One
There have been so many good performances in this Blackburn team tonight,
Showed great energy, got to the ball, made challenges.
Luton 2-6 Man City
This has turned into an exhibition game with five minutes of normal time left. City are pinging it around with so much confidence. Luton look shattered.

Into the final five minutes of normal time and Newcastle fans are bracing themselves for getting home later than they would have liked.
Having said that, Blackburn have their tails up and it is they who are pushing to win it in normal time now.

Sorry, where are those people saying City are boring?

Luton 2-6 Man City
Nathan Ake, John Stones and Bernardo Silva have also joined Erling Haaland on the bench as Pep Guardiola's thoughts turn to Sunday's Manchester derby. Rico Lewis, Sergio Gomes and Oscar Bobb are on for the closing stages.
Abdul Fatawu (105 mins)
What a strike!
This game for so long has looked like going to penalties but Abdul Fatawu may have settled it with a brilliant finish.
The Leicester substitute cuts inside from the right and bends a shot that has so much power that Mark Travers can only push into the far corner.

Michael Emons
BBC Sport at Ewood Park
That's 24 goals in the season and six in the FA Cup for Sammie Szmodics, reacting quickest after Martin Dubravka had got fingertips to Dilan Markanday's shot to push it on to the crossbar.
An excellent response just when Newcastle looked to be moving through. Great noise from the home fans and we're level again. Game on.

Stephen Warnock
Former England and Liverpool defender on BBC Radio 5 Live
It is a mistake from Lascelles.
Dubravka makes a smart save but Szmodics is there. Blackburn have fully deserved that because they have played so, so well.
Newcastle have been vulnerable all season defensively.
Luton 2-6 Man City
The bad news for Luton is Erling Haaland has been replaced by World Cup winning forward Julian Álvarez.

Danny Murphy
Former Blackburn Rovers midfielder on BBC One
What a response from this team.
Lascelles misjudges it and the shot is powerful. Szmodics, can he finish? Of course he can.
Lascelles will be kicking himself but Blackburn don't care.
Luton 2-6 Man City
Manchester City are making a treble change.
"Haaland, Haaland, Haaland," sing Manchester City's travelling fans as the five-goal striker makes his way off.
Sammie Szmodics (79 mins)
Ewood Park erupts into huge noise!
It is out of nothing as Dilan Markanday's strike is pushed onto the underside of the bar and the ball bounces out but in comes Sammie Szmodics to poke in.
We're all square and we have a real cup tie on our hands now!
Blackburn 0-1 Newcastle
Newcastle are pushing now for the second to wrap this up as Kieran Trippier drives the ball into the box from a corner, but Blackburn head it away. Just over 10 minutes of normal time remaining.
Bournemouth 0-0 Leicester
Here come Bournemouth again as now Philip Billing's shot is deflected behind. The delivery from the corner is punched clear.
Bournemouth 0-0 Leicester
Bournemouth are pushing for the winner in extra time as Marcus Tavernier cuts inside before his shot is deflected behind for a corner, which comes to nothing.
Mateo Kovacic
What, not Haaland!?
Mateo Kovacic joins the party with a fine finish from just outside the D.
There wasn't a Luton player near him.
This is Manchester City at their rampant best.
Luton 2-5 Man City
I don't think we're going to have extra-time here. There's about 20 minutes left and Pep Guardiola has still only made one change. Will Phil Foden get on?
