Alex Oxlade-Chamberlain’s 24-minute goal was all Arsene Wenger’s Arsenal needed to win the Community Shield, for the second consecutive year, this time beating the London rivals, Chelsea.
Last year, Arsenal also demolished Manchester City to clinch the trophy.
The victory is a morale booster for the Gunners less than a week to the kick-off of the competitive Barclays Premier League.
Under Jose Mourinho’s watch Chelsea had always beaten Arsenal and once last season, both coaches had lost their cool in one of the league matches at Stamford Bridge.
The England international cut inside Cesar Azpilicueta in the 24rd minute and arrowed a shot into the top corner, giving Chelsea goalkeeper Thibault Courtois no chance.
It was a goal to grace the occasion and it gave Arsenal their fifth straight victory in pre-season – and by far their most significant.
Theo Walcott, Aaron Ramsey and Olivier Giroud could have added a second but the better chances fell to Chelsea after Oxlade-Chamberlain’s opener.
Ramires squandered a free header, Eden Hazard fired a glorious chance over and Petr Cech denied Oscar and Kurt Zouma.
Arsenal have waited a while for a win over Chelsea and, although the Community Shield is no substitute for major honours, this victory can only bolster the self-belief in Arsène Wenger’s squad as they embark on a new campaign.
