Vujica has played three matches at left back for the Jets this season, adding to his tally of 14 A-League appearances overall since joining Newcastle last season.

Although unable to notch a goal or an assist during his time at the club, Vujica provides the Jets some much needed depth, both defensively and in a more utilitarian role down the left side.

The Croatian-national, who was born in Prairiewood, New South Wales, started his youth career with Sydney United, before moving to Croatia to further his football ambitions.

He played for Croatian heavyweights Dynamo Zagreb's youth team, and picked up one cap for the Croatia U/19 national side, before signing for the Jets.

Vujica resigns with Newcastle in third spot, after a teriffic start to the season under Ernie Merrick that has seen the 19-year-old play a substantial role in the Jets' defensive set up.

“Newcastle is a fantastic place, it’s been great for me both on and off the pitch,” Vujica told the club website.

“We have a strong group of players here, and I’m taking every opportunity to learn from them and continue to improve my game.

“Ernie has been great in giving me a licence to push forward and be part of some attacking play, I love being involved in the front third and help our attackers find the back of the net."

Ernie Merrick said that Vujica was "thriving" under Newcastle's new, refined playing style.

“Ivan has been thriving under a style of play that allows him to get forward and attack,” Merrick said.

“He’s a quality player, having represented Croatia at U/19 level, but he’s really come into his own over the last six months.

“He’s an impressive young man, a hard worker and a great character with all the attributes you want to see in a fullback ­– it’s exciting for Ivan and exciting for the club to see him here for the next two years.”
