West Ham vs Arsenal LIVE: Result and reaction as Gunners record biggest-ever Premier League away win

Arsenal have a fourth before the break!

Well, you certainly wouldn’t want to be in the West Ham dressing room now as the home side concede their third goal in just seven minutes.

Odegaard slips through the Trossard into the box and the Belgian shifts it onto his right before curling a wonderful finish past Areola and into the top corner.

A slew of West Ham fans head for an early half-time exit and you suspect many won’t be back after the break. A disastrous end to the half for the home side.

45+1 mins: Into the first of seven minutes of added time we go. David Moyes’ face on the sidelines says it all.

I, for one, would not want to be in the home dressing room at half-time...

Arsenal strike again before the break!

It goes from bad to worse for West Ham as Gabriel easily gets the wrong side of Alvarez from a free-kick to thunder home a header from Declan Rice’s free-kick delivery.

A superb end to the first half for the visitors, though, who have surely all but wrapped up the three points aleady.

Arsenal double their lead!

Saka missed a vital penalty at the London Stadium last season but he makes no mistake this time, sending Areola the wrong way and firing into the bottom-right corner.

A quite simply terrible ten minutes from West Ham - they have a mountain to climb now.

40 mins: Saka was onside so the penalty stands. Saka looks like he will take it...

38 mins: PENALTY! Perhaps the easiest decision Craig Pawson has had in his refereeing career.

Saka springs in behind the West Ham defence but is brought down clumsily by Areola as the Arsenal forward looks to round the Hammers’ keeper.

Areola is shown a yellow card but there’s now a VAR check to make sure Saka was onside initially...

37 mins: Another great chance for Saka as Odegaard slides the ball through to him inside the box. It’s a tight angle and Saka’s dinked effort goes just wide of the far post.

35 mins: Arsenal should be two up! Kiwior’s cross in from the left finds Saka in all kinds of space in the penalty area but the Englishman nods wide with his header.

He’s understandably frustrated with himself - that was a cracking chance to give his side some vital breathing space.

Arsenal have the opener and it’s another set-piece goal for the Gunners!

Rice swings the ball towards a crowded back post and it’s Saliba who rises highest to nod home past Areola.

That’s a soft one to concede for West Ham.

30 mins: Martinelli flashes a low cross into the box but Aguerd clears the danger just before the onrushing Odegaard can get on the end of it.
