The former Western Sydney Wanderers striker has struggled for form for both club and country recently and Luzern's patience has apparently run out now.

He's been told to find a new club and made to train by himself, according to the Swiss media, but the club stressed it was not for behaviour issues, but forΒ "sporting and strategic reasons."

"Juric has been struggling since last summer," sporting director Remo Meyer told Luzerner Zeitung. "I felt he was not 100 per cent right.

"Juric should be free to negotiate with other clubs."

Juric, 27, joined Luzern from Eredivisie side Roda JC almost three years ago but his form has been hampered by injuries.

He couldn't find the back of the net for the Socceroos in the World Cup in Russia, and was ignored completely by new Socceroos coach Graham Arnold for the Asian Cup squad.

Meyer admitted the move to make him train by himself and cut him from the squad for the next two Luzern games was specifically to "put pressure on the player."

The local press are suggesting he may move to Croatia, Poland, Russia or the Czech Republic, or to the Chinese Superleague before that transfer window shuts on February 28.
