Trabzonspor president Ahmet Agaoglu has said that his side will be looking for offers of around €30m (£26m) for goalkeeper Ugurcan Cakir.
The 23-year-old has been linked with moves to Everton and Sheffield United in recent weeks, with Chris Wilder's side reportedly having an £11m bid rejected for the shot-stopper.
In quotes attributed to The Liverpool Echo, Agaoglu said: "Our transfer budget will be determined by who is sold at the end of the season.
"In my opinion Ugurcan Cakir is one of the three best goalkeepers in Europe and a huge prospect for Turkish football.
"We want €20-€25m (£17m-£22m), it could be as high as €30m (£26m) for him but of course we also hope he stays."
Cakir has kept four clean sheets in 22 league appearances for Trabzonspor this season.
