West Ham United are preparing a bid for Jørgen Strand Larsen as they battle relegation.
Manager Nuno Espírito Santo wants a new striker in January.
Wolverhampton Wanderers are believed to value Strand Larsen at around £40m.
The 25-year-old has scored three league goals this season.
Strand Larsen impressed last year after arriving from Celta Vigo, scoring 14 times.
His form attracted interest from Newcastle United in the summer.
West Ham sit 18th and see a striker as crucial to survival.
Their current forward options are limited, with Callum Wilson the only natural centre-forward.
Nuno has also considered Ellis Simms and Haji Wright but prefers Premier League experience.
A loan move for Nathan Aké has failed.
West Ham are also pursuing Adama Traoré from Fulham.
