All the headlines will be about how poor West Ham have been and Slaven Bilic's future.

But let's not forget how well Brighton have played. It's been a superbly executed game plan by Chris Hughton's side.

They've been excellent all over the pitch and have embarrassed the Hammers.

Toxic atmosphere inside London Stadium.

BBC Radio 5 live is reporting that a fight has broken out inside the ground.

Is this Slaven Bilic's last game in charge of West Ham?

Strong words by Jermaine Jenas.

Bilic's decision to replace Marko Arnautovic with Edimilson Fernandes was greeted with a chorus of boos.

The fans are raging.

I hate to say it but it feels like one of those moments when you wake up in the morning and Slaven Bilic will not be in a job.

It feels as serious as that. His team have not turned up. Brighton have come here and embarrassed West Ham.

Around 20 minutes remaining. Some West Ham fans are making an early exit. This is going to be a long weekend for Slaven Bilic unless his players can come up with something special and produce a late response. There's no evidence of that happening.

Goalscorer Jose Izquierdo gets a rousing reception from Brighton fans as he is replaced by Solly March, whose career includes youth spells at Eastbourne Borough and Lewes.

Lewis Dunk has just smashed the ball 70 yards down the pitch. That's no nonsense defending. This will be Brighton's third top-flight clean sheet if they hold out.

Not bad by Manuel Lanzini.

West Ham need a response and the Argentine's free-kick from 30-yards takes a deflection off a yellow shirt before flying narrowing wide of the post for a corner.

This has been a highly impressive defensive performance by Brighton.

Lewis Dunk and Shane Duffy have been outstanding. Very little threat from Marko Arnautovic while Javier Hernandez has faded.

Brighton are in real control of this. They know West Ham have to throw everything at them.

Roars from Brighton fans each time their team touch the ball, Party atmosphere in the away end. Ugly atmosphere in the home ends.

Brighton hit the post through Shane Duffy's towering header from Pascal Gross' free-kick but it wouldn't have counted because of an offside flag.

What's happened to West Ham? They're all over the place.

Yesterday Slaven Bilic said a "hurricane is just around the corner" at West Ham. He could be right if his team go onto lose this.

I have just been down to the concourses and the songs the home fans are singing about their own team aren't very complimentary. They can't be repeated on here.

Some of the fans haven't returned to their seats for the second half. It's looking very bleak for West Ham at the moment.

West Ham have been pretty useless at set-pieces. Another corner leads to nothing. More groans from 50,000-plus Hammers fans.

West Ham have to do something to get this crowd going. I have had to take off my headset to see if it is as quiet as it sounds.

Shane Duffy has been outstanding in Brighton's defence. West Ham start the second half on the front foot but there is no end product. The atmosphere inside London Stadium is flat as a pancake apart from where the visiting fans are sat.

Jon Ruffell: 45 mins to save your career Bilic. But what I've seen this season doesn't inspire me that WHU will be playing in PL next season.

Ohigho Musa: I don't see Bilic and Koeman remaining in their position(s) at the end of January. I hope I am proved wrong.

A huge 45 minutes for West Ham.

Back under way.
