Liverpool 4-2 Norwich
Marcelino Nunez has a crack from distance for Norwich but his shot lacks power and Reds keeper Alisson collects easily.
Liverpool 4-2 Norwich
Liverpool full-back, or is it midfielder, Trent Alexander-Arnold clips a ball in from the right and Diogo Jota heads wide under pressure.
Difficult chance that. He does well to even reach the cross to be honest.
Liverpool 4-2 Norwich
A third Norwich goal would really set up a thrilling finale.
As it is Liverpool work the ball down the left and look for their fifth.
Borja Sainz
What. A. Goal.
Moments after Norwich have the ball in the net but see it chalked off with Borja Sainz flagged for being well offside, David Wagner's team do get a goal back.
Liverpool skipper Virgil van Dijk backs off and invites the Spanish winger to shoot from 25 yards and he finds the top right corner past an outstretched Alisson.
Watford 1-1 Southampton
The unbeaten run continues for Southampton as they make it 22 matches without defeat.
Stuart Armstrong struck in the 89th minute to equalise after Watford took an early lead through Matheus Martins' free-kick.
But they will host Watford at St Mary's in a replay to find out who will face Liverpool or Norwich in the fifth round.
Liverpool 4-1 Norwich
Grant Hanley, Onel Hernandez and Ashley Barnes had gone off moments before Norwich conceded that fourth goal.
Borja Sainz, Jacob Sorensen and Adam Idah had very little time to make any sort of impact before they were picking the ball out of the back of the net mind.
Meanwhile, Trent Alexander-Arnold comes on for the hosts who elect to give Darwin Nunez a rest with the game seemingly won.

Van Dijk has only just come on and Liverpool are winning the game with a bit of cruise. It’s got the feeling of Stamford Bridge during the week against Middlesbrough that it could get a bit ugly for Norwich.

Virgil van Dijk
Dominik Szoboszlai zings in a corner and Virgil van Dijk peels a couple of steps back to give himself a free header.
The Netherlands defender, doesn't miss from there and his effort finds the right corner, in the spot where you'd normally have a man on the post. Except Norwich don't.
Liverpool 3-1 Norwich
Ashley Barnes tries a cheeky effort from inside his own half but his shot doesn't cause Liverpool keeper Alisson any bother.
It ends up more like a back pass.
Stuart Armstrong (89 mins)
Southampton strike late!
It's a great finish. Stuart Armstrong takes a touch around Emmanuel Dennis and curls it into the bottom corner.
Late drama at Vicarage Road.

The problem for Norwich is if you push up Liverpool are very good on the break. Gibson just managed to head it up in the air and you can’t do that with Jota around. Jota doesn’t bother taking a touch he just leathers it past the goalkeeper and that is a natural striker’s goal. Jota is a far more natural striker than Nunez.
Watford 1-0 Southampton
Adam Armstrong has a shot blocked.
It just isn't happening for Southampton today.
Watford 1-0 Southampton
