Founded in 1908 as a successor to the
Sheriff of London Charity Shield, the
FA Community Shield began as a contest between the respective champions of the
Football League and
Southern League, although in 1913 it was played between an Amateurs XI and a Professionals XI. In 1921, it was played by the league champions of the top division and
FA Cup winners for the first time. As part of a sponsorship deal between
The Football Association (FA) and American restaurant chain
McDonald's, the match was officially referred to as "The FA Community Shield supported by McDonald's". with highlights shown later that night on
BBC One. The FA brought forward the kick-off time an hour earlier to avoid a fixture clash with the
UEFA Women's Euro 2017 final.
Chelsea qualified for the 2017 FA Community Shield as winners of the
2016–17 Premier League. The turning point in their season came in September 2016, following successive defeats, first at home to
Liverpool and then away at
Arsenal. Manager
Antonio Conte adopted a
3–4–3 formation which saw Chelsea embark on a 13-match winning run. and later set a new divisional record for the most wins (30). Chelsea later faced Arsenal in the
2017 FA Cup final, on course to complete a
domestic double for the second time in the club's history. A disciplined display by Arsenal, however, saw
Arsène Wenger's side triumph and secure a Community Shield spot. Like Conte, Wenger had adopted a similar tactical change during the season, playing three defenders at the back. Arsenal's noteworthy performance in the cup final was attributed to the formation switch. The 2017 edition was the first competitive fixture in English football to trial the
ABBA penalty shoot-out system, provided scores were level after 90 minutes. The format is similar to a
tiebreak in tennis, and is designed "to prevent the team going second from having to play catch-up." Unlike a traditional penalty shoot-out, which sees Team A and Team B alternate spot-kicks in an ABAB pattern, the ABBA format follows an 'AB BA AB BA' order. ==Pre-match==
