Bölükbaşı expressed his frustrations live on radio to RadyoSpor.
“Once again just before we play Fenerbahce, transfer rumours about Serdar Aziz are being published,” Bölükbaşı stated.
“Every single season this happens just before this fixture.We are not selling anybody, not Serdar and not any other player.
“Serdar came from our youth set-up, we are a big club.
“How come this same story can keep reappearing just before we play Fenerbahce?”
The 24-year-old defender has been in good form this season for Bursaspor and scored in Turkey’s Euro 2016 qualifier against Kazakhstan.
The highly rated centre back has three years remaining on his contract.
Serdar has made nine appearances for Bursaspor in the Turkish Super League this season.
