'I feel under pressure'

West Ham 1-5 Arsenal

West Ham United

More from West Ham boss Slaven Bilic, speaking to BBC Sport: "No my players did not go missing. It was bad. I feel disappointed. I feel humiliated and it’s my responsibility.

"We have good spells in the game, but we can’t do it for 90 minutes. During the game we lose composure, especially when opponents score.

"We have eight players injure and now James Collins in injured in the second minute. But I don’t want this to be an excuse for tonight’s result. I want to apologise to the fans and anyone to do with West Ham.

"We have missed Andy Carroll from the start of the season and today he came back, it’s good for him. Hopefully he is going to stay fit and West Ham can only benefit.

"I feel under pressure, I put the pressure on myself. I am not happy with the display. I don’t want to feel like this. So of course I am feeling pressure. But the pressure is not a problem. Things have to change. Quality is not enough. You have to be a team, you have to be stubborn."

If Piers Morgan is happy, Arsenal must have dome something right.

What a guy #Alexis ⚽️⚽️⚽️

West Ham 1-5 Arsenal

Hmmm. Slaven Bilic has just told BBC Sport he's been humiliated today. And he's repeated that his players don't have enough intensity in training.

The Croat has gone all out on his players - calculated risk or a good way to lose your dressing room?

'It was a big humiliaton'

West Ham 1-5 Arsenal

West Ham United

West Ham boss Slaven Bilic on BT Sport: “I am not looking for excuses. Yes we had injuries and mistakes, but we were not good enough.

"It was a big humiliation. I feel sorry for the fans and the club. We played some good games in this season, and had some good moments today even at 0-0 and 1-0 down. 

"But I have to be honest and say we don’t have the intensity and from the dedication comes the quality. We don’t have it the same as last season, even in training. We have it occasionally in games and that’s why we are so up and down. We are in a serious situation before this game which we don’t like. The players know that, but it’s not only about knowing but sacrificing and dedication for the game.

"James Collins the whole season he has a little bit of a tight calf, but he was ready to play. He did not feel it before the game but just early on in the match. It's bad luck but that’s not the reason we lost."

Andy: Okay Mr Bilic, time's up. No fight, no pace, no width, poor line-up even accounting for injuries, poor substitutions

'Our heads dropped'

West Ham forward Andy Carroll, who scored on his return from injury: "It was awful by the end. At half-time, going in 1-0, we were lucky. I thought at that time we could have got something out of the game, but as soon as it went 2-0 our heads dropped. 

"It was disappointing early on to lose James Collins - it was hard for the team and we had to alter our formation. We held on until half-time, but then let things slip. We pushed on to try and score some goals but left gaps at the back.

"We have been going through a tough spell but I think we can get out of it."

'Sanchez a classy player'

Arsenal manager Arsene Wenger speaking to BBC Sport: "We had a convincing performance and strong result. We created many chances and you could see West Ham are not a confident team at home. On top of that we had a strong performance. 

"Alexis Sanchez - it took him a while mentally to get into the game, but he can always give you something special. He’s a fighter and a classy player. You don’t find many players like him. He can always surprise you. He also has great technique as well.

"I believe we are on a strong run and it’s down to us to be mentally ready to maintain that run."

A reminder that in April, Arsenal were 2-0 up at West Ham and flapped it to draw 3-3.

None of that today.

Different Arsenal. Different Hammers.

'Alexis was amazing'

Arsenal midfielder Alex Oxlade-Chamberlain: "We were 1-0 up at half-time but we were a little wasteful and they were putting dangerous balls into the box. We knew we needed to come out strong in the second half and in the end it was quite convincing.

"Alexis Sanchez was brilliant, he gives you that speed in behind opposing defences. He’s like Sergio Aguero in many ways. You get balls up to him and he can just make things happen. He’s an amazing player and it’s great to have in the team. We are good on the counter attack and Mesut Ozil and Alexis are the first to turn and go in behind.

"When West Ham scored it kicked us back into life.We just need to keep winning games. We're Arsenal Football Club. If people don’t expect us to be there or thereabouts (in the title race) it’s a bit disrespectful. You never know what’s going to happen. We need to keep this going."

I'm re-watching Alexis Sanchez's dummy-shot for his third goal. It's glorious.

But it's his first one that takes the biscuit. There are few humans on the plant that could move a ball like he does to get away from his marker and spin into the area like that.

'A thumping victory for the Gunners'

Bradley Allen

Ex-QPR striker at London Stadium for BBC Radio London

Arsenal were at their brilliant best, and once they got themselves in front it was just a matter of time before they built on their lead. 

West Ham have to thank their keeper for keeping the scoreline down. 

A thumping victory for the Gunners and they are genuine challengers for the title.

Erm. Someone at West Ham needs to have a word with the ball boys.

A few of them mob Alexis Sanchez for his shirt - one of them wheels away in delight as he nabs the spoils.

The rest stick around for a selfie with the Chilean.

Obviously the ball boys don't really need a word - they're just having a bit of fun.

FULL-TIME

West Ham 1-5 Arsenal

A whopping performance from Alexis Sanchez.

A whopping scoreline for Arsenal.

A whopping capitulation from West Ham.

West Ham 1-5 Arsenal

Arsenal should have had 10 today. And I NEVER over-exaggerate.

Alexis Sanchez puts Aaron Ramsey in but the Welshman's shot on the stretch spins off the Hammers keeper.

West Ham 1-5 Arsenal

Into three minutes of stoppage time and Alex Oxlade-Chamberlain almost makes it six - but Darren Rabdolph saves with his feet.

West Ham have crumbled.

Might need to rename the London Stadium to the Lon-gone Stadium. It's empty now.

Some supporters have already left, but shame on you if you've left early. You've missed a wonderful forward's performance. 

Sanchez is a pearl of a player - if you're a young striker then watch this guy. It's a pleasure to sit here and watch him.

GOAL - West Ham 1-5 Arsenal

Alexis Sanchez

What's going on?

Everything's gone a bit bonkers.

Alexis Sanchez has been masterful today and now he has a match ball.

Mesut Ozil slips the Chilean in - although he looks just offside - and the finish... my word. Sanchez fakes one shot and then finally dinks the ball over Darren Randolph to nail the Hammers.

Goal rush. Fun times at the London Stadium, although not if you're a West Ham fan - streams of Hammers supporters are heading to the exits.

Maybe we're not done here.

Dimitri Payet hits a trademark free-kick from 20 yards or so that comes back off the woodwork.

The Arsenal defenders are playing musical statues and Andy Carroll nods in the rebound.

'West Ham failed'

Bradley Allen

A beautiful finish from Alexis Sanchez. West Ham failed to challenge for the ball further up the pitch, which lead to the ball coming to Sanchez. He allowed it to drift across his body before arrowing it into the far corner.

GOAL - West Ham 0-3 Arsenal

From brilliance to opportunism.

Mesut Ozil tries to trot into the West Ham area, but the ball springs loose to Alexis Sanchez on the edge of the area and the Chilean drags a shot across Darren Randolph for his second and Arsenal's third.

Four of Arsenal's last five Premier League goals have involved Alexis Sanchez in some shape or form.

The Chilean has three goals and one assist.

SUBSTITUTION

West Ham 0-2 Arsenal

Andy Carroll is on for Mark Noble.

And the West Ham striker's first touch is rusty to say the least - he tries to control the ball and it goes out for a throw-in.

Basically the exact opposite of what Alexis Sanchez just did.

'That should seal the game for Arsenal'

West Ham 0-2 Arsenal

Bradley Allen

Ex-QPR striker at London Stadium for BBC Radio London

Alexis Sanchez has been relentless all evening, and sometimes strikers get rewarded for their effort, for running hard, for never giving up. His strength there was brilliant with his small frame and low centre of gravity. That should seal the game for Arsenal. 

Andy Carroll's primed to come on. It's just 30 seconds too late.

GOAL - West Ham 0-2 Arsenal

Alexis Sanchez

Brilliance. Wonderful individual brilliance.

Alexis Sanchez is given a pass from Shkodran Mustafi that might as well have been fired from a cannon.

But the Chilean's first touch could well have been performed by a whooppie cushion - it's soft and lovely and it allows him to spin away from Anthony Makuanu and into the area, before angling the finish past Darren Randolph.

'Great reflexes on show'

West Ham 0-1 Arsenal

Bradley Allen

Ex-QPR striker at London Stadium for BBC Radio London

If West Ham somehow salvage something from this game they'll be so thankful to their goalkeeper for that superb double save. 

No criticism of the Arsenal shots - technique spot on - but great reflexes on show from Randolph.

West Ham 0-1 Arsenal

Arsenal, not content with making individual chances, have two point-blank efforts saved brilliantly by Darren Randolph.

Alex Oxlade-Chamberlain releases the overlapping Nacho Monreal down the left and the cut-back finds Aaron Ramsey - but it's saved - and Mesut Ozil's acrobatic follow-up is also superbly stopped.

Despite the flak, I've got a sneaky suspicion that #Payet might have some part in #WestHam getting something from the game #bbcfootball

Wonderful, sweeping move by Arsenal. Sanchez reversed the ball for Walcott who was up on the overlap. The England man pushed into the box then tried to square it back, but it was well intercepted for a corner.

West Ham 0-1 Arsenal

Angelo Ogbonna has just put in a block of substantial excellence.

Theo Walcott's trigger is ready to be released and the West Ham defender flies in from nowhere to stop the shot.

Andre Ayew's change eventually came, replacing Edimilson Fernandes for West Ham.

And now Walcott's off, with Aaron Ramsey on.
