1. FC Union Berlin's under-19s went down 0-3 at RB Leipzig on Saturday.
Eric Mantel, Mads Bidstrup and Joshua Wosz scored the goals for the home side as Andre Vilk's team lost for the first time since the start of October.
"As we were far off our actual performance in several areas today, the result is completely fair. We have to concede this defeat and not get annoyed for a long time, but instead make sure things go much better next weekend," added Andre Vilk.
XI: Oppermann; Labroussis, Rankic, Liebelt, Riecke; Veith, Schneider, Maciejewski, Aksakal (Krüger 89); Travassos (Gencel 67), Asllani (Ihbe 67)
Next up, Union Berlin will host Dynamo Dresden at the FEZ-Berlin complex. The match will be played on Saturday March 7 at 13:00.
