A Wembley crowd of 85,000 saw Arsenal beat Chelsea to win Community Shield
Alex Oxlade-Chamberlain scored the winner with a powerful drive into the top corner with his weaker left foot in front of 85,000.
Ramires headed wide unmarked from Loic Remy's cross as Chelsea failed to hit the target before the break.
Eden Hazard skied a chance over the bar before Oscar's free-kick was parried wide by Arsenal debutant Petr Cech.
It was the first time the former Chelsea goalkeeper had been called into action - after 68 minutes of play - and soon after he comfortably held on to Kurt Zouma's header.
Arsenal went close late on through Santi Cazorla and Kieran Gibbs in a match where both sides looked rusty a week before their Premier League opener.
It was also a landmark win for Arsene Wenger who in 13 previous meetings had failed to beat a side managed by Jose Mourhino.
