Arsenal thrashed Man city for a score of 3-0 in the Community Shield at Wembley.
The FA Cup winners took the lead through Santi Cazorla’s angled shot and added to that when Aaron Ramsey drove in a strike to finish a counter-attack.
Premier League champions City came close when Stevan Jovetic had a header hit the post and a shot saved.
But Olivier Giroud’s dipping 25-yard strike secured Arsenal’s win.
The Gunners fielded three of their four summer signings as forward Alexis Sanchez right-back Mathieu Debuchy and defender Calcum Chambers started, with the trio appearing to have effortlessly slipped into Arsenal’s trademark one-touch free-flowing football.
City were missing eight key players and, while manager Manuel Pellegrini may play down the defeat, it will serve as a warning sign before they begin the defence of their top-flight title at Newcastle on Sunday.
Pellegrini had insisted he had a stronger squad at his disposal this season as he gave two of his five summer signings in midfielder Fernando and keeper Willy Caberallo starts.
