Chelsea and Arsenal play at Wembley Stadium on Sunday in the FA Community Shield, the traditional season curtain-raiser.
Premier League champions Chelsea and FA Cup winners Arsenal played three times last term, in matches which shaped their seasons.
Here’s a look back at those games.
ARSENAL 3 CHELSEA 0, EMIRATES STADIUM, PREMIER LEAGUE (SEPTEMBER 24, 2016)
Alexis Sanchez, Theo Walcott and Mesut Ozil gave Arsenal a 3-0 lead after 30 minutes, a week before the 20th anniversary of the arrival of manager Arsene Wenger.
But Chelsea’s implosion was the catalyst for their season as Antonio Conte reverted to a 3-4-3 formation which prompted a 13-match winning run.
CHELSEA 3 ARSENAL 1, STAMFORD BRIDGE, PREMIER LEAGUE (FEBRUARY 4, 2017)
Eden Hazard scored a stunning solo goal, while Marcos Alonso and Cesc Fabregas, against his old club, were also on target as Chelsea boosted their title hopes.
Arsenal, who claimed a consolation through Olivier Giroud, were ruled out of the title reckoning and ultimately missed out on the Champions League places.
ARSENAL 2 CHELSEA 1, WEMBLEY STADIUM, FA CUP (MAY 27, 2017)
Arsenal won the FA Cup for a record 13th time and a seventh under manager Arsene Wenger with goals from Sanchez and Aaron Ramsey.
Ramsey’s winner came just a few minutes after Diego Costa had equalised. Four days later, speculation over the future of Wenger ended when it was announced he had signed a new two-year contract.
