Nicolas Pepe's 1-0 goal was delicious - the Ivorian tunneled both Nelson Semedo and Ruben Neves before placing the ball in the far post.
Then Arsenal had lined up chances during the match the first half hour and went towards the break with a lead and good confidence.
It would have time to change before the referee blew for half time.
Wolves' Willian Jose entered the penalty area and fell in contact with David Luiz.
Arsenal were penalized with both a penalty and a red card at midfield.
Ruben Neves had no problem handling the penalty.
Most red cards in the league - by far
1-1 at the break was 2-1 at the beginning of the second.
Joao Moutinho placed the lead from a distance behind Bernd Leno.
It would be worse for the German.
When Arsenal chased the equalizer, the goalkeeper was to pay a penalty cut, a few meters outside the penalty area he chose to hit the ball with his hand and was rewarded with the match's second red card.
Arsenal's ninth (!) Red card since Mikel Arteta took over as coach.
The second worst team in that category has drawn three reds.
Wolverhampton could then quite easily wait for their first victory in the Premier League after eight straight games.
