The Gunners looked disjointed in attack, which was led by Danny Welbeck and Lacazette, who occasionally dropped deeper to support Mesut Ozil in the front three.
Service was sparse as Lacazette and Welbeck worked tirelessly to unsettle the Andalucians, who deservedly took a second half lead when a neat one-two between Joaquin Correa and Wissam Ben Yedder was finished off by the Argentinian.
A first sighter in the second half was snatched at and it appeared to be one of those days, but the Emirates faithful erupted when Lacazette profited from Welbeck’s scuffed finish to tap home at the back post.
Steven N’Zonzi swept home a delightful second to win it with Arsene Wenger still searching for the best way to utilise his shiny new striker—here’s a scouting report from his performance vs Sevilla:
Positioning and movement
It was a quiet start for the France international, who was clearly instructed to to not lead an intense high press, instead occupying Nico Pareja and Daniel Carrico.
The 26-year-old was smart enough to adapt to his team-mates’ movement and dropped into a two with Mesut Ozil when Danny Welbeck closed the space down the channel, forcing Sevilla to move the ball through the middle.
Lacazette ought to score a lot of goals this season on the edge or just inside the area, with a clear thought in his head to hold his run as Alex Oxlade-Chamberlain and Nacho Monreal moved into advanced positions down the left.
Link-up with Welbeck
It would be an unlikely scenario that Lacazette is paired with Danny Welbeck this season, given Alexis Sanchez will be in contention to start in a few weeks, but it was on display from the start here.
Lacazette was happy to pivot off Welbeck’s more powerful running, with the England international driving down the channels.
The former Lyon star looked to hit the space created through the middle and far post by Welbeck’s runs, with one last ditch interception denying a simply tap-in from Welbeck’s cross.
Alert in and around the box
Alexis Sanchez’s return and a livelier Ozil should ensure a more regular look at goal for Lacazette, but with the German still to find an understanding with his new team-mate, he was forced to wait until the second half for his first chance.
Neatly laid off by Aaron Ramsey, Lacazette rushed his approach to drag his effort low to the near post, where Sergio Rico gathered comfortably.
The real difference between Olivier Giroud and Lacazette will likely be found in and around the penalty area though and the equaliser proved as much.
While Welbeck should have finished after good work from Oxlade-Chamberlain down the right, his scuffed finish was immediately seized upon by Lacazette, whose alertness should help break games open when the Gunners’ interplay is not quite working smoothly.
