Vukovic wasted no time following the conclusion of Australia's Confederations Cup campaign, completing the formalities of the deal.

Sydney FC had confirmed 32-year-old Vukovic's exit last week, stating he'd join a "top flight club".

Vukovic will replace Mat Ryan at Genk, after his compatriot spent the final six months of the 2016-17 season in Belgium on loan from Valencia before signing with Brighton & Hove Albion.

The move is significant for Vukovic who has never played in Europe, despite a brief spell with Turkish club Konyaspor in 2010.

Vukovic, who was last season's A-League Goalkeeper of the Year, also spent time in Japan with Vegalta Sendai under Graham Arnold in 2014.

The Sydney-born journeyman enjoyed an outstanding 2016/17 A-League season, keeping a record 16 clean sheets and winning the double with the Sky Blues.

Among Vukovic's competition for the Socceroos goalkeeping stocks, with a view to the 2018 World Cup, are Ryan, Mitchell Langerak, Adam Federici and Mark Birighitti.
