Bolton Wanderers manager Dougie Freedman says the Championship club have received "no concrete offers" for out-of-favour striker David Ngog.
The 24-year-old, who has scored once in 15 appearances this term, has been linked with Turkish club Bursaspor.
"There's always going to be speculation when players are out of the team," said Freedman. "We've had no official offers, but we have had two enquiries."
"David is a good player and he has a part to play."
But the Scot continued: "Right now, he has lost his form and is out of the team. He has to accept that and do something about it.
"Naturally, some players move on and some players dig deep. David will decide what he wants to do. We feel David has got to make that decision. Does he want to fight for his place or does he want to move on?"
for French forward Ngog in August 2011. In 87 games for Wanderers, he has scored 13 times.
His last start - and only goal of the campaign - came in a 2-0 win at Bournemouth on 2 November.
Freedman will look to add to his squad in January in an attempt to boost his side's faltering season - Bolton lie 16th in the Championship, 11 points away from a play-off spot and just five above the relegation zone.
With with a broken foot, a new left-back is a priority.
Speaking to BBC Radio Manchester, Freedman added: "We know exactly what we would like to achieve in January in terms of bringing people in, but you've got to be very realistic. You've got to balance the books and make sure the club's healthy going forward.
"There are one or two players that we have to move on to play some football, may that be selling them or loaning them, but as we speak there's not been any concrete offers."
