Career
His first appearance in the Yugoslav First League occurred in 1985 when he was playing in the Croatian giants Dinamo Zagreb, where he played until 1988. Still in Yugoslav First League, in 1988 he moved to Dinamo Vinkovci where he played between 1988 and 1990, having played a total of 69 top league matches in those two seasons there. In summer of 1990, he moved to the neighbour rivals NK Osijek where he will play a single but very solid season there that will earn him a call to one of the first Croatian national team matches.
In 1995 he made a big move to GAK Graz where he became one of the pillars in the defense.
His 103 games, having scored seven goals, say it all. In 1999, and already with 37 springs on his shoulders, he moved to another Austrian Football Bundesliga club Football Club Kärnten where he stayed until 2002.
Željko made part of the Croatia national football team in the earliest stages in 1991. Having afterwards continued his career in Austrian clubs, he received in 2001 a call to play to the Austrian national football team, being one of the oldest players to have made the debut for the selection, with a record 39 years.
He ended playing three matches for Austria.
