The Reds were beaten in Salzburg.Liverpool were beaten 1-0 by Red Bull Salzburg in a friendly on Wednesday July 27, a result that angered their fans. Benjamin Sesko was the lone scorer of the night as the Reds lost their second pre-season game of the summer.After a 4-0 drubbing against Manchester United, Jurgen Klopp's side recovered well, netting seven goals against Crystal Palace and RB Leipzig combined and conceding none. However, they came undone in Salzburg on Wednesday, despite mustering seven shots on target and registering 75% possession.Liverpool FC@LFCSesko's first-half goal is enough for the hosts.#LFCPreSeason6497501Sesko's first-half goal is enough for the hosts.#LFCPreSeason https://t.co/bDcNXdhjEGKlopp fielded a highly weakened team at the start, with one eye on the Community Shield clash against Manchester City on Saturday, July 30. However, much of his first team later came on as substitutes, including Mohamed Salah, Roberto Firmino and Luis Diaz. However, the Red Bulls held firm to eke out a win.Following a fast break by the Red Bulls, attacker Noah Okafor provided the perfect through ball to Sesko after a one-two with him. The 19-year-old slotted home with a right-footed shot from the center of the box into the bottom right corner. Liverpool fans were furious with their team's performance. Some of them labeled it a 'disgrace', while others even called for Klopp's sacking, trending with the hashtag 'kloppout'.Darwin Nunez, who struck four goals in 45 minutes against Leipzig, was in the starting XI but couldn't find the net. Fans called him out too, suggesting the Reds should've rather signed either Kylian Mbappe or Jude Bellingham.Here are some of the best Twitter reactions:Ste Hoare@stehoareSell them all.

However, the Salzburg defeat punctured much of the momentum they had built in the last few days.The Merseyside outfit had hit all the right notes in their previous two games before taking on Salzburg. They demonstrated free-scoring form and new signings like Nunez showed signs of finally settling in.However, it all went downhill in Salzburg, with Liverpool visibly underwhelming, struggling to finish off their chances and make their dominance count. That raises concerns ahead of the all-important clash at Wembley this weekend, with Klopp looking to win his first Community Shield after falling short in his first two attempts.The Reds play another friendly against French side Strasbourg on July 31 before they begin their new Premier League campaign on August 6 away against Fulham.
