West Ham United are preparing an opening bid for Jørgen Strand Larsen as they fight relegation.
Manager Nuno Espírito Santo wants attacking reinforcements in January.
Wolverhampton Wanderers are believed to value the striker at £40m.
Strand Larsen has scored three league goals this season for bottom-placed Wolves.
The 25-year-old impressed last year after joining from Celta Vigo, scoring 14 goals.
That form previously attracted interest from Newcastle United.
West Ham sit 18th and see a new striker as crucial to survival.
They are set to loan Niclas Füllkrug to AC Milan.
Nuno has also considered Ellis Simms and Haji Wright.
A loan move for Nathan Aké was ruled out.
West Ham are also pursuing Adama Traoré from Fulham.
