So which players stood out most?
✔️ GOOD PERFORMANCE
The Ivorian winger has had a miserable time of things since his big-money move from Lille last season but he has shown some signs of improvement in recent games.
He broke the deadlock in this game with an excellent goal, hassling Nelson Semedo, nutmegging his marker and then curling a wonderful right-footed strike into the far corner.
He had two shots on target, two dribbles and an impressive six touches in the box as he caused Wolves all kinds of problems in the first half. He now has two goals in his last three matches.
Ruben Neves: 7.4
The Portuguese midfielder showed why he is one of the most admired players in the Premier League with an outstanding performance.
He showed nerves of steel to level the scores just before half-time, smashing his penalty in the top corner and sending Leno the wrong way.
After David Luiz's sending off, he completely took over in central midfield. He had a pass completion rate of 90 per cent, had two shots on target and also made six recoveries.
❌ BAD PERFORMANCE
David Luiz: 5.0
A disastrous performance from the Brazilian veteran, who ultimately cost Arsenal all three points in this match with his third red card in just over a year.
The Gunners had dominated the first half and should have been more than a goal up heading into the break.
Then, in first-half injury time, David Luiz allowed Willian Jose to get away from him and clumsily took him down from behind. The referee had no choice but to award a penalty - which Ruben Neves buried - and send David Luiz off.
Bernd Leno: 6.0
It was a moment of stupidity from the German goalkeeper, who raced out of his area and then inexplicably punched the ball away and out of play.
Once again, the referee had no choice but to show him the red card as Arsenal were reduced to nine men for the final 18 minutes.
⭐ STAR MAN
Pedro Neto: 7.9
The 20-year-old again demonstrated why he is one of the most exciting young players in the Premier League, if not Europe.
In addition to grabbing an assist, he had an incredible five dribbles, eight crosses and six touches in the box.
A real livewire and a frightening prospect for all full-backs.
