Hamburg coach Klaus Toppmoller cast his eye over four trialists during a friendly game with local rivals VfB Lubeck on Tuesday.
Finnish midfielder Alexei Eremenko, 20, was the one who made the most impact, scoring a fine goal as the match finished in a 3-3 draw.
Brazil's Ricardo Villar, Albanian Besart Berisha and Kojo Poku, from Ghana, were also involved in the game and are now waiting to hear their fate.
