This was Wolves' first win in eight Premier League games, overcoming a Gunners side that dominated all but the last five minutes of the first half, before seeing David Luiz sent off for bringing down Wolves' new signing Willian Jose in the box, with Ruben Neves converting emphatically from the spot.
The Wolves midfield, Portuguese Maestros Neves and Joao Moutinho provided the goals that saw the men in gold and black past Arsenal.
• Moutinho shines at Molineux.
Having not scored a Premier League goal for 18 months and never having scored at Molineux, Moutinho opened his scoring tally for the season in style. Putting Wolves 2-1 up in the game, Moutinho thrashed his shot off the post into the back of the net past the helpless Arsenal goalkeeper, Bernd Leno.
Moutinho's goal saw Wolves to a much-needed win, with them climbing to 13th in the table. Nuno Espírito Santo's men will be looking to push on from this win and will be aiming to get into the top half of the league.
Moutinho ran the second half from midfield along with his fellow Portuguese midfielder Neves.
• Arsenal's shambolic discipline.
Arsenal had two players sent off in the game with Luiz and Leno both getting sent off in separate halves.
Luiz was sent off for taking down José in the Arsenal box, denying a goalscoring opportunity. Whilst Leno was sent off for handling the ball outside of his area, hitting it away whilst running out of the box.
Going 1-0 ahead through Nicolas Pepe, who went on a winding run into the box before curling his effort into the far corner. Bukayo Saka looked very threatening throughout the first half, even having the ball in the net only to see it chalked off for offside, the English wide man looks to have a promising future.
Mikel Arteta will be disappointed with the discipline of his experienced players, but Luiz does have a track record of making the odd rash decision in the penalty area.
• Wolves almost back to full strength.
With the addition of José in the now-closed transfer window, Wolves look a much stronger outfit, with players like Adama Traore and Pedro Neto playing well against the Gunners and the back four seems to work well; it's hopefully going to ensure a positive run of form in the Black Country.
Raúl Jiménez is still out injured and Wolves will not be the same team until he returns, but with José hoping to make a similar impact on the Wolves squad.
After Patrick Cutrone went to Valencia in Spain on loan until the end of the season, Nuno must be hopeful that his current options will be enough to see them climb up the table in the second half of the season, especially after making no transfer dealings on deadline day.
The formations have been changing on a weekly basis in recent games, but tonight Wolves seemed to find success with four at the back, even with the goal and the offside goal they seemed solid at the back and will hope to build on the performance.
