Barnsley boss Mark Robins admits top-scorer Daniel Bogdanovic may leave the Yorkshire club in the summer.
The 30-year-old, who is out of contract at the end of the season, has been in inspired form for the Tykes this season, scoring 14 goals.
But he now looks set to Oakwell after turning down an improved contract offer earlier in the week.
"We have reached the limit we can go to for Daniel," Robins told the Sheffield Star.
"He will now move on or come back to sit down with us again, but I know there are a few other clubs interested as well.
"We have offered a contract and he has turned that down. People are well within their rights to try and get the best deal possible, but we have made the best offer we can for this club."
