New signing Milan Jovanovic made a 45-minute debut for Liverpool as a largely inexperienced reserve side lost 1-0 to Kaiserslautern in Germany.
The Serbia forward, brought in on a free transfer from Standard Liege, played the first 45 minutes before he was withdrawn by manager Roy Hodgson.
By that time the Reds were behind, courtesy of Ilian Micanski's close-range tap-in.
Jovanovic was one of only two members of the squad who had played at the World Cup, the other being defender Sotirios Kyrgiakos who lasted 77 minutes.
