The Sky Blues had announced Vukovic's impending departure to an unnamed club last week and the two-year deal with the option to extend the contract by a further 24 months was confirmed by the Belgian outfit on Wedensday (AEST)

The A-League goalkeeper of the year replaces Socceroos teammate Mat Ryan who played 17 games for the Belgian Pro League side last season on loan from Valencia before making a big money transfer to Premier League newcomers Brighton & Hove Albion.

Wanted this since I was a boy. Flying back home to say my goodbyes before I embark on the biggest year of my football career. 🇧🇪🔵⚪️ pic.twitter.com/QbRyS7t7lA — Danny Vukovic (@vuka20) June 27, 2017

Vukovic claimed his first A-League title last season with the shot stopper a key contributor in Sydney's record breaking campaign. The 32-year-old saved a penalty in the grand final against former club Melbourne Victory to make up for his three previous defeats in the final with Central Coast Mariners and Perth Glory.

"I am very fortunate to have had the best season of my career since joining Sydney FC," Vukovic said on leaving Sydney.

"It has been an amazing 12 months for me and my family, a year I will always remember, and I would like to thank the members and everyone at the club for an unforgettable experience.

"I'm very sad to leave but to have such an unbelievable opportunity so late in my career is something that I just couldn't turn down."
