The Palace ground staff are required to come on and take off a flare that the Hartlepool fans have thrown on. Their solution is to shove it in a bucket with a lid, meaning they walk off with the thing leaving a big smoke trail behind them. Rubbish job, but someone has to do it.

Wolves are not far off an equaliser as Chiquinho whips in a cross and Fabio Silva rises but directs his header over the bar.

Overall Palace have been the better team. But credit Hartlepool. After half-time they've had a spark.

Danny Ward nearly settles this for good, but his first-time shot in the box comes back off the post.

Liverpool target Fabio Carvalho is replaced in the dying moments.

A lot has happened since the 19-year-old put Fulham ahead.

Five minutes of normal time left. A professional job by Stoke who are heading for the last-16 for the first time since 2015.

Almost a dream for young full-back Omotayo Adaramola, who has just come on for Palace. He is just denied a follow-up finish to Michael Olise's saved shot by a last-gasp Hartlepool challenge.

Superb save by John Ruddy as he stretches out a hand to keep out Kieran Dowell's effort. That keeps Wolves just about in this but some home fans aren't confident because they are heading to the exits.

It's been night and day with what they produced recently under Benitez. The big thing is possession, they have kept the ball really well and reacted quickly when losing it. High energy all over, and I think Lampard has made a difference already.

Jamie Sterry sees an effort tipped past the post by Jack Butland as Hartlepool look to spark some late drama.

Brentford bring on 18-year-old defender Fin Stevens for Rico Henry.

Peterborough v Chelsea in the fifth round?

They're heading into the next round which will be played in the first midweek of March.

Huddersfield have the ball in the net from Ollie Turton's back-post finish, but he is well offside.

Barnsley still have hope.

This one is heading to extra time unless someone can find a winner in the next 10 minutes.

Nathan Redmond tries to be the hero but his shot from distance is straight at the goalkeeper.

We all love a triple change, don't we?

Manchester City are cruising so Pep Guardiola sends on 18-year-old Liam Delap, Bernardo Silva and James McAtee.

Jack Grealish, Riyad Mahrez and Phil Foden have made way.

Ten minutes of normal time left.

They haven't had a lot to cheer during the match but the near 5000 supporters have really got behind their team in the last ten minutes. On the pitch, they've had a couple of strikes which have forced Jack Butland to make saves.

This one is still not settled. Barnsley have given a much better showing second half than first. Do they have anything left in the tank to stop Town reaching round five?
