Wolves have had a €15million (£12.5m) bid rejected for Udinese defender Thomas Kristensen.
Vitor Pereira's side have been keen to strengthen in defence in the transfer window after a difficult first half of the season, with Ivory Coast centre back Emmanuel Agbadou their only addition so far having arrived from Reims for £16.5m.
They were hoping to bring in Lens star Kevin Danso after agreeing a loan move with an option to buy, but Tottenham hijacked their move, while they had also been linked with a sensational swoop for former club captain Conor Coady.
