Alvaro Morata missed a penalty on his Chelsea debut as Arsenal won an uncharacteristically feisty Community Shield in a shootout at Wembley.
Record signing Morata – a late substitute – dragged a poor effort wide moments after goalkeeper Thibaut Courtois had blazed over in a first use of a new penalty shootout system.
Premier League champions Chelsea had gone ahead through Victor Moses, before Pedro was sent off for an ugly lunge on Mohamed Elneny.
From the resulting free-kick, debutant Sead Kolasinac headed the Gunners level to take the match to penalties.
The shootout – the first in English football to follow the ABBA format – saw Chelsea miss back-to-back penalties to allow Olivier Giroud to win the match from the spot.
