Nathan Tella, who looks recovered from that injury, drives a shot in from outside the box but it's saved.

Leicester are not playing well.

Marc Cucurella looks as likely as anyone to create something for Brighton. His blocked cross brings his side a corner.

Kurt Zouma is the first man to the delivery, though. He clears with his head.

Jurgen Klopp will say just carry on - the results have been very good. Going forward they are averaging three goals a game, that is unbelievable. When you've got three strikers in the top four of goal scorers in the league that tells you that they're flying. Especially when you have three, not just one, it's a bit ominous.

There's been a lot of talk about last year - it was one of those games where from a Liverpool fan's point of view. Virgil Van Dijk went off injured, there was a penalty and sending off and then Sadio Mane was offside by a fine margin, everything went against Liverpool. You have to try and forget those things, you can't see it as another game because it's a derby but they've just got to try and stick to the habits they've had up to now.

I don't think Jack Grealish is intimidated or thinks he's not as good as anyone else - but at Aston Villa I wouldn't go as far to say that it was a one man team but it was all on him. It was always going to take him time in a Guardiola side where it's so technical and everyone needs to know exactly what they're doing even in training sessions.

Guardiola will stop training sessions and say 'no - I don't want you to take it with your left foot here, I want you to take it with your right foot and pass and take two touches'. Grealish is not really a two-touch player, he likes to dribble with the ball and draw the foul. It's always going to take time - Guardiola was spot on in saying no we're not waiting for next season, he has to put pressure on Grealish now.

I do believe Grealish is good enough to adjust but he has had almost his whole career around 'give the ball to Jack and see what he can do' - that's not what Guardiola is about.

I'm not surprised it's taken him time - the Grealish of Aston Villa is gone, because that is not what Guardiola is looking for.

The players are back out, but will do a little warm-up before play restarts.

The fan affected has been brought to hospital now we believe.

Webster off, Duffy on. Another blow for Brighton. Saying that, Shane Duffy has been in good form this season.

Adam Webster is down again. That calf injury has gotten the better of him. Shane Duffy is going to be coming on in his place.

Jarrod Bowen is inches away from connecting with a diving header in the middle as West Ham drive forward again. The Hammers are well on top now.

Nathan Tella looks in some amount of pain here. He basically does the splits after losing the ball and has hurt his groin. He's going to try to play on.

Adama Traore breaks again!

This time he does use his support, feeding Raul Jimenez but Charlie Taylor times a tackle to perfection on the edge of the Burnley box.

The visitors are living dangerously, though, leaving so few players back when they attack.

The reaction of the Everton fans after the Brentford game wasn't nice, it certainly wouldn't have been nice for the players to get that amount of stick. You can understand it - I know a lot of Everton fans and they're absolutely decimated at the moment, they can't see any positives, they're going through a rough spell.

When your confidence is down, it is really down. You tend not to try things, other times things can go against you. But it is a derby - for Everton a bit of a cup tie. The fans will be right behind them from the start, people from Liverpool are passionate about football and that will show on the terraces. It's not going to be easy, but it doesn't matter how well Liverpool are playing or how poor Everton are playing things can still happen.

Amazon say the ambulance is coming to take the man affected in the crowd, but he is stable. The hospital is next door.

Once that happens, the players will come back out.

Adrenalin: Fantastic assist from the Southampton goalie to pass it straight back to Jonny Evans for the easiest of tap ins. Would Forster perhaps do any better? I'm not sure...

Totum: Remember the good old days when goalkeepers tried to catch crosses (rather then punching by default) and attempted to gather in shots rather than parrying the ball back into play?

The first chants of “Rafael Benitez” go up - from the Liverpool fans. Might be rather a lot of goading tonight.

So close!

The woodwork denies Wolves as Adama Traore charges away on the break. He has Raul Jimenez in support but he goes for it alone, beats Nick Pope but his shot thumps off the underside of the bar and bounces away from danger.

West Ham are turning the screw now. A free-kick into the mixer falls at the feet of Craig Dawson at the back post but his attempt to steer it to a team-mate is cut out. Nervy moments for Brighton.

The medics are still up on the upper tier of the Graham Taylor stand helping whoever needs help in that part of the stadium. The referee has just been out to have a chat with some of the broadcasters to update them on the situation.

The game has been stopped for about 15 minutes, some of the Chelsea staff have been out and put some balls on the pitch so I suspect if this game is to restart then they will have to have a short warm-up.

At the moment I don't think that's going to happen soon.

What an effort!

Pablo Fornals so close to making it 2-0!

Vladimir Coufal's cross is headed down by Michail Antonio and smashed against the underside of the bar on the volley by Fornals. Didn't cross the line on it's way down.

Amazon say the person in the crowd with the medical emergency is recovering. But the players won't come out until the situation is cleared up.

When that happens there will be a five-minute warm-up.
