Pasquali, who has been in the youth ranks with Dutch giants Ajax, will join A-League newcomers Western United for its debut campaign in the competition next season.

The 19-year-old made two A-League appearances for Melbourne Victory in 2016, as a 16-year-old, before crossing to Ajax and has been a regular in national youth squads in the past 12 months.

Pasquali is currently in Cambodia with the Olyroos (Australian under-23s) as they begin their qualification campaign for the Tokyo 2020 Olympics. 

They play three games in the space of four days against Cambodia (Saturday), Chinese Taipei (Sunday) and South Korea's under-23s (Tuesday).

"It's exciting to get him back and see him take a step up in his career with his first senior contract," his father Tony said.

"He'll get the opportunity to be part of a first team squad and train and play with some really good players.

"He's two years older for starters, and, in the meantime, he's been able to get some experiences under his belt."

Pasquali will relocate to Melbourne once his current contract finishes at the end of May.

Pasquali has signed alongside Apostolos Stamatelopoulos and Dylan Pierias, who currently play for A-League outfits Adelaide United and Melbourne City, respectively.

Socceroo Josh Risdon has also committed to Western United.
