Arzani, 20, has been sidelined since injuring his ACL in his senior Celtic debut last October and has been in rehab ever since, following surgery by Pep Guardiola's hand-picked surgeon in Barcelona.

But in the early hours of this morning, he finally came off the bench to play against Hibs for the Celtic reserves side at their Lennoxtown training base as the latest step towards a full first team return, possibly next month.

He made an immediate impact, dribbling upfield and delivering key throughballs into the box as well as firing off ferocious shots on goal.

Arzani is expected to play a key role in the Olyroos' bid to get to Tokyo 2020 when their qualifying tournament kicks off in Thailand in January.

And the former Melbourne City signing – now on loan to Celtic from Manchester City – will also be likely to bring his have-a-go X-Factor to the Socceroos' attack for the World Cup qualifiers.
