Arsenal recovered from successive Premier League defeats in emphatic fashion with a comprehensive 3-0 victory over Southampton at the Emirates Stadium.
It was the visitors who started the brighter of the two teams, going close through Nathan Tella on the edge of the penalty area after he had evaded the attentions of Takehiro Tomiyasu.
Adam Armstrong then forced a fine stop from Aaron Ramsdale from a similar position, receiving a pass inside from Kyle Walker-Peters before unleashing an effort towards the bottom corner.
Just as the crowd inside the Emirates Stadium began to make their feelings heard, Arsenal cut through Southampton with sweeping precision.
A gorgeous back-to-front move released Bukayo Saka down the right hand side and when the England international pulled the ball across goal, Alexandre Lacazette was on hand to guide the ball beyond debutant Willy Caballero.
Five minutes later Mikel Arteta's side had doubled their advantage. Tomiyasu sent a deep cross towards Kieran Tierney in space at the back post and, after he couldn't quite divert the ball back across goal on two ocassions, his header into the six yard box was met by Martin Odegaard stealing in at the front post.
The host were purring. Lacazette was sent through for a third soon after but he outpaced, before Saka then called Caballero into action after he was released by a clever backheel from Odegaard six minutes before the interval.
Arsenal continued to lay siege to the Southampton after the interval, threatening on the break when Odegaard fired over from a Saka lay-off.
The Gunners thought they had sealed all three points when Gabriel bundled in from a corner at the back post, but the linesman raised his flag and VAR confirmed the Brazilian had drifted into an offside position.
However, his perseverance was rewarded three mintues later when he rose highest from a Saka corner and powered Arsenal into a 3-0 lead.
Arteta's side continued to pour forward in what was their most menacing attacking display of the season. Gabriel Martinelli curled an effort off the post before Saka followed suit from the opposite flank after a clever give-and-go with Thomas Partey.
Southampton threatened on a couple of instances through Tella, but Arsenal were comfortable in the end.
Here's how both teams rated.
