Alvaro Morata and Thibaut Courtois missed penalties as Arsenal won the Community Shield with a dramatic 4-1 shootout victory over 10-man Chelsea.

The season curtain-raiser between Premier League champions Chelsea and FA Cup winners Arsenal finished 1-1 after Sead Kolasinac, two minutes after Pedro was shown a straight red card, cancelled out Victor Moses' opener at Wembley.

An English football first followed as the 'ABBA' penalty shootout was deployed and the Gunners prevailed to extend their winning record at Wembley to nine straight games, including two in penalty shootouts.

Trailing 2-1 in the shootout, Courtois took Chelsea's second kick but failed to equalise, blazing over, before club-record signing Morata fired wide.

That handed Arsenal the initiative, allowing Alex Oxlade-Chamberlain to score before Olivier Giroud netted the decisive strike to secure the Shield, and a timely boost ahead of their Premier League opener against Leicester on Friday Night Football.

Alex Iwobi's direct running twice forced Courtois to be alert early on, while Danny Welbeck headed at the goalkeeper, who was beaten by Alexandre Lacazette only for the striker to see the ball rebound off the post on 22 minutes.

Per Mertesacker had to go off on the half-hour mark after being struck by Gary Cahill's flailing arm in the Arsenal box, with summer signing Kolasinac replacing him.

Chelsea's first attempt of note came on the counter-attack on 35 minutes as Pedro received a fine cross-field pass from Willian and drew a fine save from Petr Cech at his near post.

Two minutes later, Willian was adjudged to have dived in the area after Hector Bellerin's mis-control, although replays showed there to be contact before the Brazilian clipped his own heels.

Chelsea took the lead within moments of the restart as Cahill returned a clearance back into the Arsenal area where Moses was lurking, and he chested and volleyed beyond Cech.

The goal promoted a celebratory dive from Nigerian, a nod to his costly dismissal for simulation in May's FA Cup final defeat to the Gunners.

Pedro was sent off after catching Mohamed Elneny on his Achilles 10 minutes from time and Arsenal scored from the resulting free-kick as Kolasinac headed Granit Xhaka's cross beyond Courtois from close range.

Morata, brought on with 16 minutes remaining, headed Cesc Fabregas' late free-kick wide from an offside position before Arsenal claimed their second Wembley victory over Chelsea in 10 weeks at the shootout.

Man of the match

Sead Kolasinac - All the focus ahead of kick-off was on the big-money summer acquisitions Antonio Conte and Arsene Wenger had brought to their respective clubs this summer. But, instead, it was a man who arrived for nothing that caught the eye.

Brought on in place of the injured Mertesacker, Kolasinac endeared himself to the Gunners faithful with a robust performance, littered with energetic runs from deep and capped by the equaliser.

What's next?
