It's another one.
Arsenal counter from a Lens attack. Bukayo Saka runs for ages and finds Takehiro Tomiyasu on the overlap. He crosses and captain Martin Odegaard volleys into the bottom corner from 12 yards.

What a first half for Mikel Arteta. I don't think he would have thought it would be this comfortable.
Bayern are still being held 0-0 by FC Copenhagen. Manchester United could do with the German champions winning that one.
Benfica, who have yet to pick up a point in the competition this season, are 3-0 up against Inter Milan.
Joao Mario has scored a hat-trick against his former club in that one.
And Real Madrid are still leading Napoli 2-1 thanks to Jude Bellingham's 16th goal of the season.
Arsenal 4-0 Lens
Arsenal's first attack in a while almost brings a fifth goal. Bukayo Saka slips in Gabriel Martinelli, but he smacks his shot into the side-netting.
Arsenal 4-0 Lens
Angelo Fulgini spins and shoots on the edge of the box for Lens but it's straight at David Raya.
Arsenal 4-0 Lens
Lens, a good side when they're losing 4-0 based on this. Elye Wahi smacks a ball across the box but Arsenal deal with it.

Mikel Arteta has definitely changed Arsenal's style this season. It's been a different Arsenal. They try to win more second balls.
Arsenal 4-0 Lens
Lens midfielder Nampalys Mendy is booked for a foul on Gabriel Jesus.
Arsenal 4-0 Lens
Facundo Medina has recovered from that and demonstrates it by smashing a shot off the post from 25 yards.

Raya has cleaned Medina out there. He may have got the ball but he's clattered him.
Arsenal 4-0 Lens
Lens swing a free-kick into the box and David Raya misses the ball, but clatters Facundo Medina. No foul.
Arsenal 4-0 Lens
To be fair, Lens have weathered the storm now. The game has been fairly even in the past 10 minutes. The damage is done but it's not one-way traffic any more.
Arsenal 4-0 Lens
Too early to be wondering what Arsenal's biggest Champions League win is?
Anyway it's 7-0 against Sparta Prague in October 2007.
Arsenal 4-0 Lens
A few Newcastle fans will probably be wondering why that wasn't a penalty when PSG's was. And the answer to that question is... I have no idea.
Arsenal 4-0 Lens
Lens whip a free-kick into the box and a few of their players are screaming at the referee for a penalty.
A replay shows the ball hit Kai Havertz's leg and then his arm.
There's a brief VAR check but no penalty is the decision.
Arsenal 4-0 Lens
Surprisingly the possession figures are 50-50. Arsenal doing somewhat more with their share of the ball.
Arsenal 4-0 Lens
This is the joint-fastest an English side have scored four in a Champions League game, along with Manchester United v Brondby in November 1998. That ended 5-0.

Gabriel Jesus looks up for it tonight, doesn't he?

Arsenal's combinations have been very good. The French, so far, haven't been connecting.
Arsenal 4-0 Lens
Bukayo Saka down again after another foul. Mikel Arteta might want to consider just bringing him off now with the game won.
