Galatasaray rising star Ozan Kabak has been linked with several clubs over the current season.
Turkish-Football reported back in October that Kabak had attracted interest from Manchester United who have been scouting him.
Roma have also been keeping close tabs on the 18-year-old defender.
Reports in the Turkish media last week claimed that Kabak had struck a €9m deal with Cardiff City.
The reports later turned out to be false.
Turkish-Football have been informed by sources at Galatasaray that Kabak has not been sold.
Offers from Premier League sides have been made but the club do not want to sell in January.
Galatasaray are currently in talks with the young defender over signing a five-year contract extension that would see his €7.5m release clause increased to €20m.
The Lions are concerned about his current release clause as it does not reflect their €20m valuation.
The Istanbul giants are confident that Kabak will decide to stay put for the time being. The Turkey international rose through the Galatasaray academy before breaking into the first team.
Kabak has a close bond with the club and Galatasaray believe he would want to leave if it were beneficial for the club as well as himself.
The young defender is currently a first-choice defender for the reigning Super Lig champions.
Head coach Fatih Terim has given Kabak a chance to prove himself in the first-team. An opportunity rarely given to young players at the big three in the Turkish top-tier.
