Dr David: Birmingham v Coventry has to be the best case for abandoning fa cup replays. Just settle it now.
Newcastle 0-0 Oxford
Huge result for Oxford! In the hat.
Southampton 1-1 Tottenham
Tony Pulis
Former Stoke and West Brom manager on BBC Radio 5 Live
I thought Tottenham were going to go on and get another goal and win comfortably. Fair play to the Southampton manager, he's changed the system, the game's been stretched and open and Tottenham have kept giving the ball back to Southampton. In the last 20 minutes, they looked the team to go on and win the game.
Southampton 1-1 Tottenham
All over at St Mary's. There's going to be a replay.
Reading 1-1 Cardiff
Teddy Howe heads onto the roof of his own net from the corner!!

All over at London Stadium.

Conor Hayes: How the owners can sit up there and do nothing about this mess at West Ham. They are business people and have no love for the club. The only way we can move forward is to get them out
Portsmouth 4-2 Barnsley
A goal fest! Pompey are through to the fifth round.
Burnley 1-2 Norwich
Not sure when he came on but Teemu Pukki nearly made it 3-1 - his effort well saved by the feet of Joe Hart.
West Ham 0-1 West Brom
Michail Antonio's cut-back finds its way through to Mark Noble on the edge of the box but he smashes it over the bar.
What a chance!

RegularJon: You’d have thought Newcastle was one of the givens in an accumulator today. Can’t even get that right!
Does this mean Pompey are going to be first on Match of the Day?
Richie, Liverpool
Reading 1-1 Cardiff
