This is a completely different game. The mood in the Emirates has changed. Brighton sense they can get something from this.

In the stadium the red card for Rice was the last outcome that supporters thought was coming. They were calling for Veltman to be punished for kicking Rice and not the ball.

It's only on the replay you see that Rice nudged the ball and it looks as though the referee got that decision right. Two very needless yellow cards for Rice.

Incredible scenes.

Declan Rice, who has already been booked, is shown a second yellow card after a bizarre incident.

Rice gives away a soft free-kick before falling down to the ground after Joel Veltman appears to kick the ball at him.

The midfielder is then shown a red for what looks like time wasting.

Huge moment!

Declan Rice has been sent off.

What a start to the second half by the home side!

Lovely stuff by Jurrien Timber and Declan Rice almost leads to a second.

Then a corner which Gabriel puts wide.

Arsenal's final 45 minutes before the international break.

Will they build on their lead?

Back under way.

The teams are on their way back out. No need for Brighton to panic. They looked like they might be overwhelmed in the opening stages before settling. Fabian Hurzeler will be reasonably happy with what he has seen from his side so far but they need to respond in the second half.

As it stands, Arsenal are heading into the international break with nine points from three games and without conceding a goal.

Their next game?

A blockbuster. Away to Tottenham on 15 September.

Garett: Way too soft by Dunk. Got beat on an aerial header by one of the smallest players on the pitch in Saka, and Saka did not even jump.

John: Bukayo Saka winning an aerial duel against 6 foot 5 Lewis Dunk...Is there anything he can't do?

Boos around the Emirates. Not for Arsenal's performance but for one or two decisions by the officials.

We're still playing deep into stoppage time. Thomas Partey has just been booked for dragging back Joao Pedro.

Arsenal are pushing for a second at the end of the first half.

Leandro Trossard lines up a shot... straight into the arms of Bart Verbruggen.

A goal behind and now decisions going against them on the pitch.

Brighton have a battle on their hands.

Now a free-kick for Brighton about 25 yards out. Jack Hinshelwood whips it into the danger area and it comes off Gabriel.

Corner for Brighton? No, says referee Chris Kavanagh.

The visitors are not happy.

Brighton had an attacking free-kick, poor delivery, easily gathered.

That lead to that passage of play there.

It's a soft goal to give away just before half-time.

Naughty by Declan Rice. He goes in late on Joel Veltman.

VAR is going to have a look at this. A caution for the England midfielder in the end. And a yellow for protesting Brighton boss Fabian Hurzeler.

Brilliant from Kai Havertz.

Not great defence from Lewis Dunk, he has to be stronger and he should no be getting pushed out of the way by anybody.

Brighton are looking for a free-kick, but I don't think it is.

You knew exactly what Havertz was going to do as he lifts it over Bart Verbruggen.

Three games. Three assists.

Bukayo Saka has had a great start to the season.

And let's not forget his goal against Wolves.
