Crystal Palace are set to table a formal offer for Wolves striker Jorgen Strand Larsen.
Sources have told BBC Sport that Palace's interest in the 25-year-old forward has intensified in the past 24 hours with a bid now expected from the Selhurst Park club.
Wolves are open to selling the Norway international this month provided they get a fee close to the £55m they rejected from Newcastle for the striker during the summer transfer window.
Leeds have already seen an offer of £40m rejected by Wolves, and as things stand the Elland Road club are reluctant to go much higher.
