Incredible - it's not what you'd expect to see in the Premier League - the defending is awful from Arsenal. It's a really long throw and no one seems to touch at the near post, it flicks on and bounces up. Slomehow Christian Norgaard is first in there and heads it straight into the far post. The goalkeeper can't get anywhere near it. It's all about desire, determination and putting it into the right areas.

The supporters here can't believe what they're witnessing.

The home crowd have gone wild again.

Arsenal fans are stunned.

Bryan Mbeumo has been equally as good.

He wins a throw-in for Brentford deep in Arsenal's half.

Emile Smith Rowe has been magnificent.

He drives it from inside his own half over to the left and plays in Bukayo Saka.

It's pulled back to Reiss Nelson, who lays it off to his right but there's nobody there.

Brilliant from Arsenal, they're finally getting in some better areas. Forward runs are what's needed and when it falls to Granit Xhaka you wonder if the net will ripple but he blazes it over the bar.

Mikel Arteta will be delighted with that sort of effort - much better from them.

Mads Sorensen replaces Kristoffer Ajer at the back for Brentford.

Reiss Nelson is on for Gabriel Martinelli in attack for Arsenal.

Arsenal are hotting up.

Emile Smith Rowe, to Bukayo Saka, a cut-back for Nicolas Pepe... cleared.

Loose ball just inside the box... Fired over by Granit Xhaka.

Bukayo Saka has made a difference already. He links up with Kieran Tierney, who tries to weave into the box with his first touch.

Kristoffer Ajer slides in recklessly and is lucky not to make contact with Tierney, as the ball races away from the Arsenal defender.

Another long ball is won by Ivan Toney in the air, beating Ben White.

It's flicked on and finds its way at the feet of Bryan Mbeumo, who has space and time to shoot.

Bernd Leno pulls off a good save before the flag goes up. Dangerous.

Sergi Canos drives into the Arsenal box and gets a shot off but Bernd Leno parries it away!

Ooft.

Gabriel Martinelli flicks it on at the near post but can't quite direct the header into the far corner.

Very, very close.

Pablo Mari heads off to get a bit of treatment after being winded but Arsenal carry on without him.

Ben White is pressed but he finds Bukayo Saka, who flicks it on and Kieran Tierney wins a corner.

I spy John Murray and Michael Brown...
