Australian international midfielder Tom Rogic will link up with Celtic at their winter training camp in Spain.
The Central Coast Mariners player, who turned 20 in December, has enjoyed a rapid rise down under, having only moved to the A-League side in January last year.
Making his debut a month later, Rogic has since made 28 club appearances, scoring five goals
He made his international debut in a friendly with South Korea in November, before going on to play in four games at the East Asian Cup, which included a 9-0 win over Guam and 8-0 victory over Chinese Taipei.
Rogic has six months left to run on his deal with the Mariners, but Celtic have made no indication if they would consider a permanent move for the player.
Speaking to the Sunday Morning Herald, Mariners' director of football, Scottish-born Lawrie McKinna, said: "This is a great opportunity for Tomas to train with Celtic's first team squad.
"Celtic are in their mid-season break and are busy preparing for their Champions League matches against Juventus starting in February.
"Tom will undoubtedly learn a lot from the experience."
Rogic was also linked with a trial at English Premier League side Reading this month but decided instead to take up the option of a one-week stint with Neil Lennon's men.
