That was amazing, that's what football does, that unity - that will make Bukayo Saka feel great.

On comes Bukayo Saka, who receives a standing ovation from everyone at Brentford. Lovely touch.

He replaces Folarin Balogun.

Nicolas Pepe tries to squeeze through in the box now but he's crowded out by two defenders on either side.

But here's a change for Arsenal...

Good possession from Arsenal there, good deliveries, overloading in good areas. Little flicks and tricks. Wonderful little wedge form Kieran Tierney but that just wasn't to be.

Arsenal are looking a bit sharper. Nicolas Pepe pounces on a loose clearance and finds Kieran Tierney.

His cross is over Emile Smith Rowe but he keeps going, plays a smart one-two with Pepe and almost gets a shot away. It's hoofed clear just in time.

Let's face it they couldn't get much worse. Arsenal are finally driving at the Brentford defence and giving keeper David Raya some work. Not before time.

Ben White tries to stop it reaching Ivan Toney near the touchline but he's clattered into him.

Free-kick to Brenford.

Bryan Mbeumo beats Pablo Mari with ease in the box with a few nice stepovers which receive a roar of approval from the home fans.

Emile Smith Rowe has been comfortably Arsenal's best player.

He shows his quality here with a superb turn in the middle and he sprints through.

He gets into the box and has a shot but it's straight at the keeper. What a chance!

Brentford don't want to create that lull, they want to keep the pressure on and the tempo up. It's been good from Brentford - we're still seeing Arsenal passing the ball and moving it around but they don't look very confident. There's no real urgency.

That's better from Arsenal.

They are able to bypass the press and Emile Smith Rowe blocks a clearance on the right.

Nicolas Pepe switches it across to the left, via Ben White.

Brentford are pressing high again. Calum Chambers loses it but gets lucky when he wins a throw-in.

Emile Smith Rowe immediately takes a hold of it, finds Granit Xhaka, who tees up Kieran Tierney but his low, drilled cross is straight at the keeper.

From kick-off, David Raya launches it long for Ivan Toney and Brentford's Ethan Pinnock has a chance to put in another long throw-in.

It's won by a Brentford player but it's comfortably in Bernd Leno's arms a few seconds later.

Big 45 minutes coming up.

Can Brentford hold on? Can Arsenal grab an equaliser?

Mikel Arteta is frowning in the dugout.

Arsenal are ready to go but Brentford are hanging around a bit in the tunnel.

Arsenal are winless in each of their last 15 Premier League matches in which they were trailing at half-time (W0-D4-L11).

The last time the Gunners managed to turn a half-time deficit into a win, was at West Ham United on 9 December 2019.

We've seen some good movement from Arsenal, some nice football, getting wide and high - but it's the pace of it and that's what needs to be lifted.

You can play in front of a side all day long but I want to see the tempo increase, Arsenal started by playing the ball long because they were under a bit of pressure but now they've started to take more risks in front of goal but the pace is down. Yes, they're missing players but there are still enough players to do better than what they are doing.

Arsenal tried to get the possession and get moving Brentford were a bit nervous, which you'd expect at the start. They got into the game, more passing more bravery they turned the tempo up.

Finally after them hitting the post it went out to the left hand side and there was Sergi Canos with a wonderful strike. It really lifted the stadium - probably a deserved first-half lead.
