Last season, Vuskovic emerged as one of the Bundesliga's biggest surprises. At Hamburg, he was an undisputed first-team regular under manager Merlin Polzin, making 30 competitive appearances and recording six goals and one assist.
Consequently, the centre-back has attracted the interest of several top clubs. FC Bayern Munich is reported to be weighing a move for the 19-year-old.
FC Barcelona are also said to be monitoring the 19-year-old, with initial talks already reported between club and player.
