Game over.

It should be three!
Joe Willock in acres of space in the box but he volleys over from 10 yards out.
Gabriel Martinelli (15 mins)
He just cannot stop scoring.
Arsenal score twice in three minutes and Gabriel Martinelli has both goals.
This is a stunning goal from the player who models himself on Cristiano Ronaldo, taking Reiss Nelson's ball in the box, turning and curling a delightful strike into the far corner.

That boy again.
The two summer signings link up for the opener.
Kieran Tierney on the overlap, whips in a cross to the near post which Gabriel Martinelli stoops and flicks in a wonderful header into the roof of the net.
The £6m Brazilian looks to be a bargain, his third goal in just his second start for the Gunners.

A real let-off for the hosts.

Wolves
Wolves skipper Conor Coady: "We made it hard for ourselves, it's a tough place to come but we dug in. To keep a clean sheet is very pleasing and the win is very special.
"We've always got to feel our way in to the game, that's the sort of team we are. We'd have liked a bit more of the ball so we could play but we dug in and it's a very satisfying win.
"It's huge for us. We don't want to make up the numbers, we want to compete to win. We would have liked to have played better today but we won and that's the most important thing."

Bright start from Arsenal.
