The former Sevilla and Schalke striker is currently on loan with Danish side Brondby and has admitted he could yet depart Celtic permanently.
Teemu Pukki may have already played his last game for Celtic after the 24-year-old hinted that his loan deal with Danish side Brondby could be made permanent in January.
The Finland international arrived at Parkhead from Schalke 04 in August of 2013, with the Bhoys shelling out £2.2 million to bring the former Sevilla youngster to the club.
But Pukki struggled for goals in his first season with Celtic, scoring just seven times in 33 appearances for the Hoops and was sent out on loan to Brondby on a season-long deal prior to the close of the summer transfer window.
The agreement gave Brondby the option to buy the former HJK Helsinki favourite at the end of the season and after scoring four goals in just five games for his new team, the club are reportedly considering moving to make the transfer a permanent one this January.
Speaking in quotes carried by the Herald Scotland, Pukki hinted that a deal could be done, though he remained largely tight-lipped on the subject.
"You never know what will happen with Celtic. Right know I am concentrating on enjoying my football and just thinking about the next match,” he said.
"If something happened with a permanent transfer, I would have to make a decision."
Any sale could allow Celtic to pursue a permanent deal for John Guidetti, the Swedish striker signed from Manchester City on loan a few months ago.
The 22-year-old has proven a hit at Parkhead thus far, with four goals in his first six games for the club, including the opener in Sunday’s 5-0 win away at Ross County.
At present, however, it remains unclear as to whether City are keen to keep Guidetti, though he has proven popular with his new Celtic teammates who praised his skill and overall team-play in a recent interview.
