Maruping was a regular for Phunya Sele Sele last term but has been unable to win the favour of new coach Veselin Jelusic.
"The boy's contract with Celtic ends at the end of the season," the source tells KickOff.com.
"But the club do have an option to extend, but the player's camp hope it doesn't come to that and also at this stage Celtic are promising nothing.
"His representatives are currently working very hard behind the scenes pushing for a loan move for the player in January, that's if Celtic allow him to join another team in the upcoming transfer window."
Baroka, Golden Arrows, Highlands Park and Luc Eymael's Free State Stars are said to be monitoring the former University of Pretoria man.
"There is big interest from Baroka and Arrows. The way I see it Arrows are more serious than Baroka but there is also an option of Highlands Park but which is for a loan move. They are said to be interested in a loan move.
"Stars coach Eymael is a big fan of Maruping and has even been directly in contact with the player asking him why is he not playing at Celtic.
"I know very well that Rantsi [Stars boss, Mokoena] is not a fan of loan deals because of the Thela Ngobeni incident, he feels it destabilises the team. So if if they release Maruping Free State Stars might be the first to pounce. He is actually very high on the Free State Stars list.
"Baroka wants to sign him as a free agent but the player's camp wants them to have him on loan first so he can stay fit. The boy is frustrated; at one stage the club went to play in Cape Town but the coaching stuff decided to get someone who played in the Celtic MDC team as a backup player instead of him."
Celtic CEO Khumbulani Konco denied knowledge of Maruping's unhappiness or of interest in the 26-year-old's services.
"I'm not aware of that, it's the first time I'm hearing about this," Konco says.
