Everton want a penalty...

Instead it's a free-kick right on the edge of the box and a booking for Arthur Masuaku for a high boot that nearly catches Theo Walcott on the head.

A good save from Fabianski.

A lapse in concentration, Tosun bearing down on goal had Walcott and Calvert-Lewin, but he went himself.

That happened because they played quicker, got the ball into the forwards quicker.

The groan from the Everton fans was more than audible when West Ham scored their second. The home side have been dozy in possession for the vast majority of this first-half.

Now it's West Ham's defence that is parting at every opportunity. The Hammers give the ball away in midfield, back off and back off as Cenk Tosun drives into the area, but it's not the cleanest strike and Lukasz Fabianski palms it away.

One Everton player who can come out of this half with a bit of credit is Theo Walcott.

Not sure if he meant that Marco van Basten-cum-Ronaldinho style lob, but he nearly caught Lukasz Fabianski out with a first-time volley from out wide.

The West Ham keeper does well to tip it over the bar.

'Blowing Bubbles' is ringing out around Goodison Park now.

West Ham are brimming with confidence, Everton are all over the shop. Marco Silva is scratching his chin on the touchline and wondering how on earth they turn this around.

I cannot believe Jordan Pickford has tried to play there. The ball is dead, they shouldn’t be in danger. He tried to pick a pass 20 yards in his own half. A really really bad goal to give away.

What a finish from Yarmolenko. He opens up the goal and curls it in the far post, Pickford absolutely no chance.

No one can accuse Idrissa Gueye of not putting his body on the line - the Everton midfielder takes one right in the gut to win possession back on the halfway line. He doesn't even flinch.

But the Toffees give it away, again, and West Ham look to hit Marko Arnautovic on the break immediately. Jordan Pickford comes rushing out of his box to bail his side out.

That is one of the easiest saves Fabianski will make in his career. The ball in is right on the six-yard line, Tosun is stretching, it is a difficult header but he has got to do more.

Everton need to get the ball wide to Walcott and cross it, that is where their goals are going to come from.

Billy Boy: Think my telly is playing up - switched it off and on again but it’s still showing West Ham are in front.

What a chance for Everton.

I mentioned Lucas Digne earlier, and it's the left-back who goes past his man out wide and clips in a lovely ball for Cenk Tosun.

The Turkey striker is unmarked, six yards out, but heads straight at Lukasz Fabianski.

Should have buried it.

The West Ham fans have been in fine voice since kick-off. They have taken it up a notch now. They are all on their feet chanting their club anthem. I think you know the one?

Marko Arnautovic must be a nightmare to defend against. Quick, strong, good feet.

The Austrian backs into Mason Holgate and thinks he's been hauled down in the box, but referee Martin Atkinson doesn't agree.

I was expecting Everton to build on their impressive start, they looked organised, Sigurdsson was getting on the ball a lot.

But now West Ham have come into this game and looked good. They look calm now, their tails are up.

Here's a stat Toffees fans won't want to read - Everton have not won any of their last 10 Premier League games when conceding the first goal.

And one for Ukrainian Premier League fans - Andriy Yarmolenko is the first Ukrainian to score in the Premier League since Andriy Voronin in May 2008.

Nice.

Again Everton give it away in midfield.

Sloppy from Idrissa Gueye, whose pass is cut out and Mason Holgate has to scramble back to slide in and tackle Marko Arnautovic on the edge of the box.

Goodison Park is about to boil over.

Jordan Pickford is forced into action, but it's a simple take for the England goalkeeper after Issa Diop got a toe on Felipe Anderson's low free-kick.

It's all West Ham at the minute.

That should give West Ham a bit of confidence.

Marko Arnautovic is the danger man - every time he gets on the ball he looks like causing trouble.

The West Ham forward picks out Andriy Yarmolenko once again on the counter, but this time Everton recover quickly to get men behind the ball.

The Toffees are wobbling.

Where did that come from? A straight ball, Marko Arnautovic beats the two centre halves and he's got so much time.

I thought he would strike it but he plays it to for Yarmolenko who was unmarked. What a simple goal to score.

To conceded a goal like that is absolutely shocking.
