Liverpool lost 1-0 to RB Salzburg in their final preseason game before their crucial Community Shield matchup against Manchester City.
Last week, the Reds destroyed RB Leipzig 5-0, but they were unable to overcome a resolute home defense in the second half.
Darwin Nunez and Harvey Elliott both missed golden opportunities before Benjamin Sesko, who had beaten Liverpool defender Ibrahima Konate on the break, brutally put the home team in lead.
In the second half, Jurgen Klopp made several substitutions, but Salzburg goalkeeper Nico Mantl and his defense held strong, giving the Premier League heavyweights an unpleasant evening at the Red Bull Arena.
