Celtic manager Ronny Deila has told Herald Scotland that John Guidetti must prove that he wants to stay at the club ahead of the summer transfer window.
The Bhoys are pushing towards a historic treble in Deila's first season in charge, and Guidetti has certainly played his part in that.
The Swedish international, 22, is on a season-long loan from Manchester City, and has hit 14 goals in 32 games for the Bhoys this term.
However, Guidetti's future is complicated. Out of contract at City this summer, Guidetti will be a free agent - making him available to join any club of his choosing on a free transfer.
Reports from Dutch website Voetbal international suggested on Monday that Guidetti's former club Feyenoord have already made a contract offer to the striker in a bid to tempt him back to Rotterdam, but his future is certainly still up in the air.
It remains to be seen whether Celtic will make an offer to keep him, but manager Deila told Herald Scotland that Guidetti must first prove that he wants to play for the Bhoys before any deal is on offer in this summer's transfer window.
"He (Guidetti) has to come back and say that he wants to play for Celtic and then we can sit down and talk about it. If not then he will go away," Deila said.
"We have done everything we can do and he wanted to wait. I speak with him regularly but we will have to wait and see what happens," he added.
With not long left until the end of the season, Guidetti is running out of time to prove to Deila that he wants to stay at Celtic - and this could all push him closer to a return to Feyenoord, barring a surprising change of heart from the striker.
