Ajax have been linked with a move for Paraguay international Oscar Cardozo according to the Milliyet.
Trabzonspor recently valued the former Benfica striker at €10 million.
The Black Sea Storm have underlined that they want to keep hold of Cardozo but could consider offers above their valuation.
The Paraguayan international joined Trabzonspor from Benfica on a €5 million move this summer on a three-year deal.
The 31-year-old striker scored 172 goals in 293 appearances for the Portuguese giants.
Cardozo has scored a total of 18 goals and provided four assists in all competitions for Trabzonspor this season.
Trabzonspor are currently sixth in the league on goal difference. The Black Sea Storm share the same points tally as fourth placed Bursaspor and fifth placed Başakşehir.
