Arsenal are preparing another substitute. This one is telling of where Mikel Arteta's mind is...

Gabriel gobs off at one of his team-mates. The one who let Rayan Ait-Nouri run at him.

Standards are high when you're going for the Premier League title.

Rayan Aït-Nouri has been playing an auxiliary winger recently and is happy to burst forward down the right flank.

However, Gabriel is too wise for that and levers the Wolves sub off the ball. Goal-kick.

Before the set-piece is delivered from the right, there is another Wolves change.

Two of them in fact.

Rayan Aït-Nouri comes on for Matt Doherty, while young debutant Tawanda Chirewa is replaced by Pablo Sarabia.

Chirewa receives a big hug from his gaffer for a tremendous shift. A night the 20-year-oldf will never forget.

Wolves can't nick something here, can they? Imagine Mikel Arteta's reaction if they do.

The home side have a corner...

Leandro Trossard's evening is over.

The Arsenal winger's number is up and will be replaced for the final 20-odd minutes by Gabriel Martinelli.

As it stands Trossard is the matchwinner and sending Arsenal to the top of the tree...

Bet Mario Lemina's eyes widened when he was told he was going up top. No wonder he was smiling when he came on.

The Gabon international, usually a midfielder, is working hard to create space for his team, pulling out wide in the channel and cutting in before shooting straight at David Raya.

The ball is knocked into the Arsenal box, with Mario Lemina playing as the striker.

But David Raya is alert and comes out to clear the danger.

Not a great deal of action at the moment. You might be able to tell.

Arsenal are managing the game nicely, keeping the ball and trying to wear down Wolves.

When the ball does go into a penalty area, Leandro Trossard tries to twist and turn but can't find room to shoot.

Instead he lays off to Kai Havertz, whose cross is wayward.

Arsenal fans are making all the noise inside Molineux. A fun Saturday night out in Wolverhampton so far.

Mikel Arteta rather wisely told assistant Albert Stuivenberg to get away from fourth official Darren Bind as he was in danger of getting embroiled in an argument with Gary O'Neil's backroom team.

The Wolves bench were unhappy at the free-kick that was awarded against Mario Lemina and Stuivenberg was telling them why it was awarded.

Bond was already fielding the questions.

Of course, if you're an Arsenal fan you are loving this. Any win will do tonight.

Now, I'm not saying this game is dull. But the talk among some in the BBC Sport office has turned to Saturday night television.

Martin Odegaard's inswinger is headed out twice by Wolves before Boubacar Traoré thumps clear.

Wolves midfielder Mario Lemina is punished for clocking Jakub Kiwior in the head as they both challenged for a header.

A free-kick for Arsenal in a very dangerous place.

About 25 yards out, on the left hand side of the area...

No shots on target yet for Wolves in the second half.

The home fans, fully aware of their situation with so many players out injured, are trying their best to rally the team.

Textbook technique from Kai Havertz.

A ball is lobbed back into the Wolves box and the German watches it like a hawk before swivelling to hit a volley goalwards.

Straight at Jose Sa, though.
