Triantis spent the latter half of last season at Easter Road, making 14 appearances in all competitions. Two of those came under David Gray at the end of the campaign, with him playing as a ‘number 6’.

The 21-year-old has been part of Sunderland’s First Team squad this summer and has made appearances in the English Championship and the EFL Cup.

Alongside his club exploits, Triantis has also been capped at Under-23 level for the Socceroos.
