Morten Rasmussen is set to return to Celtic at the end of a loan spell in Turkey and is keen to know where he stands at Parkhead.
The Danish forward saw his short-term deal with Sivasspor come to an end on Wednesday, and the club will not be seeking an extension.
The 26-year-old netted just three times in 11 appearances and will be sent back to Glasgow.
Rasmussen still has 18 moths left to run on his Celtic contract, but he does not appear to figure in Neil Lennon's plans.
A January switch elsewhere has been touted, but the Denmark international wants his future resolved one way or another after struggling to make an impact during his two years in Scotland.
"I will be back in January and will hold talks with Celtic as soon as possible," Rasmussen told the Daily Record.
"Nothing has been said so far, I'm waiting to find out.
"As things stand, I will be coming back to train with the squad but I don't know what the club have planned for me.
"If Celtic want me to stay then I will train hard, do my best and try to get in the team."
He added: "I have been in this situation for a while but it's not ideal.
"I just have to wait and see what January brings. It would be good to get my future sorted."
