Mazis, originally from Canberra, joined the Scottish giants in February 2018.

He earned a deal after impressing on trial.

The ex-Belconnen United midfielder spent time with Celtic's Under-20s and reserves teams, but never made a first-team appearance and trained with Melbourne City last pre-season.

Now the 19-year-old has linked with Serie C outfit Triestina, owned by Melbourne-based property developer and Metricon magnate, Mario Biasin, who is also a director of Melbourne Victory.

"Firstly I would like to say thanks to everyone at @celticfc for the support these last two years, itโ€™s been a pleasure ๐Ÿ’š๐Ÿ€," he Mazis posted on Instagram.

"But I am excited and ready for the next chapter at @u.s.triestinacalcio1918 ! Letโ€™s get to work ๐Ÿ”ดโšช #ForzaUnione #LM19."

It is believed Mazis has signed a one-and-a-half-year deal with the Italian side, taking him through to the end of the 2020/2021 season.
