Arsenal are now at the bottom of the Premier League after a humiliating defeat to Manchester City on Saturday.
The Gunners have lost all three of their opening games this season, a feat they have never suffered since 1954.
City captain Ilkay Gundogan and striker Ferran Torres scored in the first 12 minutes and any hope Arsenal had of an unlikely comeback was ended when midfielder Granit Xhaka was sent off for lunging into a challenge on Joao Cancelo.
A trademark teasing run from £100m man Jack Grealish set up Gabriel Jesus for an easy third just before the break, then Rodri guided home a fourth from 20 yards just after it.
Such was his side’s total control that City manager Pep Guardiola had used all three substitutes within 16 minutes of the second half starting. It turned into an extended keep-ball session for the hosts, who finished off the rout with Torres’ second six minutes from time.
Guardiola’s counterpart and former assistant Mikel Arteta looked shell-shocked in the other technical area as Raheem Sterling – twice – Aymeric Laporte and Riyad Mahrez wasted opportunities to increase the margin of victory still further.
By the end, Arsenal had managed a single shot – off target – and 19% possession. They are still to score in the Premier League this season and immediately after the international break play Norwich, the team they replaced at the foot of the table.
