Austrian striker Sasa Kalajdzic is attracting Premier League interest.
The 21-year-old has drawn attention with his performances for Admira Wacker this season and has scored five goals in his last five games including the winner in Saturday's 2-1 Bundesliga win over Hartberg.
The Daily Mail says Crystal Palace are keen with concerns over their goal return and Christian Benteke considering his options with a year left on contract.
Brighton and promotion-chasing Leeds United have also watched Kalajdzic while Red Bull Salzburg, Espanyol, Nice and Genk are among a growing list of clubs to have made initial enquiries.
