Dundee United striker Nadir Ciftci has turned down the club's offer of a new contract.
The 23-year-old Turk has 12 months remaining on his current deal at Tannadice Stadium.
Ciftci, who scored 16 goals last season, joined United from NAC Breda in 2013.
"After extending my two-year contract in December 2013 with an extra year, I have decided that after three years at Dundee United I will be looking for a new challenge," he is quoted as saying by Sky Sports News.
"I'm satisfied with my development so far and therefore I must thank the coaching staff who played a big part in that. I would also like to thank the fans and the club, who have always been behind me."
Cifti has scored a total of 33 goals during his time at Dundee United.
