Arsenal won the Community Shield on penalties, ending Manchester City's silverware run, after a 1-1 draw with the treble champions on Sunday.
Leandro Trossard's badly deflected equalizer 11 minutes into stoppage time at Wembley forced the shoot-out for Mikel Arteta's side.
Cole Palmer's brilliant curler had given City the lead late in the second half. Still, penalties were missed by Kevin De Bruyne and Rodri before Fabio Vieira converted the deciding kick in the annual Premier League season opener.
With City's first penalty kick, De Bruyne hit the crossbar, and Aaron Ramsdale saved Rodri's shot, while Arsenal converted all four of theirs.

Arsenal's celebrations were far more frantic than expected in a glamour friendly. Still, their joy highlighted the months of misery endured since they squandered an excellent opportunity to win their first title since 2004.
Last season, City became only the second English club to win the Premier League, Champions League, and FA Cup in the same season.
Their fifth Premier League victory in six seasons came at the cost of Arsenal, who blew an eight-point lead at the start of April to end five points behind the champions.
Arsenal had a point to prove versus City as they sprung into tackles with the kind of urgency that usually comes with a championship decider, showcasing £160 million worth of new arrivals in Declan Rice, Kai Havertz, and Jurrien Timber.
While Arteta and his players ran around the pitch, taking in the wild celebrations from their fans, they might want to remember that the Community Shield winners have only won the Premier League once since 2011.
City broke the trend in 2018, and it is much too early to bank on Arsenal following in their footsteps.
Arsenal led the standings for 248 days last season and fell short, forcing Arteta to confess that stopping the champions this season will require an "unheard of" points total.
