The 29-year-old attacking midfielder is a free agent having left Romanian club FC Dinamo Bucuresti — where he played 73 games in the past two years.
But the eight-time Croatian youth international is now understood to be on the verge of signing for another overseas club.
And in an added bonus to its 2017-18 prospects, firebrand winger Fernando Brandan is making a play for a shock Round 1 return from a serious knee injury.
Brandan required surgery after injuring his anterior cruciate ligament in training in March.
The season-opening clash against Brisbane at AAMI Park on October 6 would be seven months post injury, but the 27-year-old is back running and recovering well.
A Round 1 return is seen as a best-case scenario, but the club’s medical staff is confident Brandan will feature early in the season.
