Swiss reports have linked 27-year-old Juric with Super League club FC Sion during the January transfer window, before his Luzern contract expires at the end of the season.
Juric almost moved to Swiss giants FC Basel in August, before the transfer collapsed amid reports that he failed a medical.
The ex-Western Sydney man has struggled for game time at Luzern this season, due to injuries and selection, which Socceroos coach Graham Arnold said was the cause of his Asian Cup omission.
Sion are in the market for a powerful striker and it has long been rumoured that Luzern are eager to offload Juric before he becomes a free agent.
Luzern boss Rene Weiler recently refused to be drawn into the situation.
"I do not want to speculate on what will happen to our striker Tomi Juric during the winter break,” Weiler said.
He added that he knew nothing about Sion’s reported interest and wouldn’t discuss whether Luzern would offer the Australian a new deal.
Juric was surprisingly left out of Australia’s Asian Cup squad announced last week, but comes after making only seven appearances for Luzern this season.
The striker, who set up Australia’s 2015 Asian Cup final winner, hasn’t scored in the Super League all season - with his only goal coming in the Swiss Cup.
Juric has previously been linked with German clubs as well as English Championship outfit Reading.
