Arsene Wenger's side got their hands on their first piece of silverware of the season at Wembley today.
Victor Moses put Chelsea ahead just after half-time, but Sead Kolasinac equalised following Pedro's sending off.
Arsenal held their nerve in the shoot-out which followed to win the trophy.
And they looked pleased to get their hands on the Community Shield after Olivier Giroud scored the final penalty.
Even Alexis Sanchez - who was left out of today's squad because he's lacking match practice - looked happy with the win.
