Liverpool drew first blood in this season's rivalry with Manchester City with a 3-1 win in Saturday's Community Shield. Trent Alexander-Arnold opened the scoring, firing Juergen Klopp's side ahead in the 21st minute of the 100th edition of the annual clash between league champions and FA Cup winners. City's new Norwegian signing Erling Haaland, brought in from Borussia Dortmund, missed two chances to mark his debut for the champions with a goal but Pep Guardiola's side were missing their usual fluency.
