The 20-year-old hasn't played since an ACL injury on his Hoops debut in November, but now stands to travel to the Balkans alongside Tom Rogic for the qualifying round match.

However he is still highly unlikely to play in any part in the game as he rebuilds his fitness ahead of the new season but his inclusion in the European squad underlines his future with the club.

Arzani, who has returned to Celtic on loan from Manchester City after completing his rehabilitation at the English club, wgill now be focused on breaking into the first team as a regular under new boss Neil Lennon.

Last season the Scottish champions were dumped out of the Champions League in the third qualifying round by AEK Athens, so it's likely Lennon will choose a strong squad.

“It is a dangerous tie for Celtic,” Lennon said. “We will not take anything for granted.

“Sarajevo are the champions of their country and are to be respected.”

Arzani's return, whether he makes a competition debut or not, is a promising sign for the prodigious Aussie, who has spoken about the mental health challenges of suffering a long-term injury.

Arzani famously doubted he would ever fully recover from the injury in June this year, but both his Celtic and Manchester City coaches have praised his mindset and physical recovery.

Celtic play Sarajevo tomorrow morning, 3:45am (AEST).
