Liverpool had scouts present in the second division of German football football to cast an eye over Hamburg centre half Mario Vuskovic, according to a report from Bild.
Premier League club Wolves also hold an interest in the Croatian defender, who is highly rated. Vuskovic signed for Hamburg following a two-season loan spell from Hajduk Split.
Hamburg missed out on promotion back to the Bundesliga last season after losing in the play-offs. The 20-year-old, according to the report, has now been watched by Liverpool.
