This comes after 2-1 victory over Chelsea in the FA Cup final on Saturday evening.
Liverpool have secured their spot in the Shield game by emerging Premier League champions for the first time in 30 years.
In 2019, they took part due to Manchester City winning both the league and the FA Cup.
Liverpool have won the Community Shield 15 times in their history, with the last coming in 2006.
They are currently tied with the Gunners for the second-most wins in the trophy’s history, with Manchester United the only side to win it more times (21).
Jurgen Klopp’s men will then begin their Premier League defense on the weekend of September 12.
