Erling Haaland, Kevin De Bruyne, Mohamed Salah and Virgil van Dijk; two world-class goalkeepers in Ederson and Alisson; and arguably the two leading coaches in the game in Pep Guardiola and Jurgen Klopp. With so much A-list talent and winning pedigree between Manchester City and Liverpool, Saturday's Community Shield clash (stream live on ESPN+ in the U.S. at 12 ET) is more than a curtain-raiser for the new season, it is a showcase of excellence that has become the defining game in English football.
