Union Saint-Gilloise taught Liverpool's young guns a lesson with a 2-1 win in Brussels, though the Reds were already into the last 16 of the Europa League.
Jurgen Klopp fielded the club's youngest-ever team in Europe with an average age of 22-and-a-half years old and, truth be told, they struggled.
Union Saint-Gilloise took a deserved lead after 32 minutes as Mohamed Aurora beat the offside trap and took the ball past Caoimhin Kelleher before firing home.
The Reds were back on level terms on 39 minutes as Jarell Quansah bagged his first goal for the club, a composed and powerful finish after the ball fell to him from a corner.
