Southampton have made a double change to try and get back into this as Stuart Armstrong replaces his namesake Adam while Kyle Walker-Peters is on for Thierry Small.

Wolves attack early as Nelson Semedo gets down the right and swings the ball across the face of goal but he has no team-mates there ready to pounce.

Right then, what drama could the next 45 minutes serve up?

Th 3pm kick offs in the FA Cup are getting back under way.

Plymouth manager Steven Schumacher, speaking to BBC Match of the Day: "We're really proud. We knew it was going to be a really tough day. We wanted to make our fans proud and I think we did that.

"A lot of the credit this week has to go to Keith Downing, who is a really good out-of-possession coach. We had to be organised and the back three had to defend their goal really, really well.

"I think both goals were from their full-backs, but I can't be too disappointed with our players. I think their legs went at the end. Ryan Hardie is devastated. He normally strikes the penalties better than that. He'll be disappointed but he can't dwell on it too long.

"We're moving well and going in the right direction as a club. It's a great club to work at. That's the aim - to get to the Championship."

Chelsea

Chelsea assistant manager Arno Michels, speaking to BBC Match of the Day: "We had so many shots and so many chances.

"There were so many opportunities in the box today, but they defended very well, very deep but very disciplined. It was not easy to convert all these opportunities.

"We stayed in touch with Thomas [Tuchel]. Right now we have to wait for the next day to see what's going on.

"We have a few problems. Mason [Mount] we had to take out, Hakim [Ziyech] we had to take out, Azpi felt his hamstring. We had a few muscle problems, but they're hopefully only little ones."

New first team coach Ashley Cole has been observing from the media seats with a member of Everton’s analytical team and has just dashed down to the dressing rooms in time for Frank Lampard’s half-time team talk.

It all went a bit off the boil at Etihad Stadium after that breathless start but I don't think we've seen the last of Fulham, especially on the break - Neeskens Kebano in particular is just rapid down the left and Kyle Walker will have to be careful now he is on a booking.

Final Score

Duane Holmes goal separates the two sides. Sorba Thomas has been a constant thorn in the side for Barnsley. He is quick and a real threat for the home side. Whenever he gets the ball the crowd get excited. Could be a long afternoon for Barnsley even though its only 1-0 at the break.

Palace are leading 2-0 and deservedly so. They've been the better team. The Hartlepool manager can get them in at half time; they need to reorganise, maybe try and change the system to a flat back four and get extra men in advanced positions. They need the next goal, but it has been very comfortable for the hosts.

Peterborough have not had a lot to cheer about this season but they are 45 minutes from the fifth round.

No shock on the cards so far.

Frank Lampard's Yerry Mina has scored the only goal as Frank Lampard's Everton lead non-Frank Lampard's Brentford at Frank Lampard's half-time.

The half comes to an end with a booking for Kyle Walker.

More goals to come?

Viktor Gyokeres' goal has Coventry of the Championship 45 minutes away from knocking out a Premier League side.

Town lead. They've been the better side and could have extended their lead, but Barnsley are still in it.

And the whistle goes for half time with Norwich ahead thanks to Kenny McLean's header just before the break.

Brentford defenders back off, back off, back off as Demarai Gray runs forward from midfield but he shoots just over from the edge of the box.

Three minutes added on.

The final action of the first-half is a Hartlepool half chance that Omar Bogle fires wide on the turn.

It has been largely comfortable for Palace.
