Djulbic flew out of Perth on Tuesday night and will undergo a four-day trial with the possibility of a move before the end of the January transfer window.

The 25-year-old underwent a trial with SpVgg Greuther Furth, another second division German side, in early December but was unsuccessful in securing a deal.

Djulbic will miss this weekend's clash against Newcastle at EnergyAustralia Stadium.
