The trio impressed sufficiently on trial to be awarded deals with the club but Utrecht also sought opinions from those who have worked with the youngsters - including Pim Verbeek and Frank Farina.

On Utrecht's official website, Sarota said: "This is a great place for me to develop." New Socceroo Oar said: "It's a club with a bright future and I look forward to be part of it."

Oar has penned a five-year deal with Zullo and Sarota agreeing three-year contracts. Roar have not revealed how much they have received for the trio.
