With just 18 months remaining on his contract, Olmo is attracting interest from a number of top European clubs during the January transfer window.
However, according to Sportske Novosi, Wolves have made a formal approach for the playmaker, indicating that they are willing to pay £21.3m.
As he looks to earn a spot in Spain's squad at Euro 2020, Olmo has acknowledged that he is open to leaving the Croatian giants.
Head coach Nuno Espirito Santo has not been shy in stating that he wants to make a number of new signings before the end of the month. body check tags ::
