Arsenal boss Arsene Wenger finally had reason to celebrate against Jose Mourinho's Chelsea, having failed to win in any of his previous 13 attempts against the Portuguese.

His side beat League champions Chelsea at Wembley to win the Community Shield for a second season in a row thanks to Alex Oxlade-Chamberlain, who scored the winner with a powerful drive into the top corner with his weaker left foot.

Chelsea came close to scoring themselves, as 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 Peter Cech.

The former Chelsea goalkeeper was called into action for the first time after 68 minutes, 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, just one week ahead of their Premier League opener.

Mourinho's Premier League champions are yet to win a game in pre-season but will believe that the combination of second-half substitute Radamel Falcao (making his debut) and Costa will improve their attacking threat.
