How the Community Shield unfolded in images and online.
Wenger is still yet to beat Mourinho in a league game but the Gunners lifted the first silverware of the season, just as they did last term at Wembley Stadium.
Alex Oxlade-Chamberlain opened the scoring in the first half with a fantastic strike and it proved the winner as Arsenal defended resiliently, with Chelsea looking distinctly off the pace.
Chelsea fans were disappointed throughout on Twitter.
Time to give up on playing 4-3-3.. Should hv played Oscar from starts #CFC— I'm bhu Nyendak (@tenzinnyendak) August 2, 2015
Yeah it might sting the players a little now, but this will help get us even more serious & we'll be ready come the season start. #CFC— Brendan Naiker (@BrendanN37) August 2, 2015
Arsenal fans, however, were naturally full of joy.
A few pundits and ex-players also took note of the Gunners on Twitter, as Wenger and co celebrated yet another victory at Wembley.
After half-time, Chelsea knocked on the door and Eden Hazard missed a great chance to put the Blues back on level terms.
But they couldn't break Arsenal down in the end, as the Gunners continued their strong pre-season. West Ham are next up for them in the Premier League. Petr Cech and more will be smiling going into it.
If Koscielny isn't MOTM there should be a stewards inquiry !!!!— Rodney Marsh (@RodneyMarsh10) August 2, 2015
Looked resilient today Arsenal. Encouraging signs if they are to challenge for the title. Expect to see a lot more from Chelsea this year.— Joseph Barton (@Joey7Barton) August 2, 2015
