The 24-year-old Dinamo Zagreb player's agent, Danko Dikic, told BBC Sport: "There are some big, big clubs interested in Vukojevic."

Dikic refused to confirm whether Celtic are one of them, despite reports that he has already agreed terms with the Scottish champions.

Dinamo are understood to want around £3.9m for Vukojevic.

Dikic says that he will meet the defensive midfielder next week to begin consideration of his future.
