West Ham United are preparing an opening bid for Jørgen Strand Larsen as they battle relegation.
Manager Nuno Espírito Santo wants attacking reinforcements in January.
Wolverhampton Wanderers are believed to value the striker at around £40m.
Strand Larsen has scored three league goals this season for the bottom-placed side.
The 25-year-old impressed last year after joining from Celta Vigo, scoring 14 times.
His form previously attracted interest from Newcastle United.
West Ham sit 18th and see a new striker as crucial to survival.
Callum Wilson is currently their only natural centre-forward.
Nuno has also considered Ellis Simms and Haji Wright.
A loan move for Nathan Aké has failed.
West Ham are also pursuing Adama Traoré from Fulham.
