Wolverhampton Wanderers have reportedly rejected a bid from Besiktas for defender Ronald Zubar.
The offer of £1.8m was dismissed before the 26-year-old departed for the club's pre-season trip to Ireland, according to the Express & Star.
Zubar, whose current contract is due to expire in 12 months, has hinted that he wants to extend his stay at Molineux.
"I'm happy at Wolves but I don't know what's going to happen – there could be players going, players coming in," he said.
"The club knows what I want, but we haven't talked about a contract yet.
"Seven of us are in the last year of our contracts and we need to find out if we're staying, if we're getting new deals or if we have to go."
Wolves signed Zubar from Marseille in July 2009 for a fee in the region of £2.5m.
