Wiretapped phone-calls imply the 59-year-old subjected officials and referees to threats in the run-in to Fenerbahce's title victory last season
The files, consisting of telephone conversations between Yildirim and the other leading figures in the match-fixing scandal, were leaked online a day after being handed to lawyers.
"You are afraid to show up for a dinner. One day you will come, but from now on you will get no support from me," read an excerpt from a conversation between Yildirim and TFF vice chairman Levent Kizil.
When met with the reply: "I would like to come, but Mahmut [former TFF vice-president Ozgener] didn't want to. What should I do?", Yildirim answered: "Who on earth is Mahmut?"
Another phone conversation, between Ozgener and then-Istanbul BB chairman Goksel Gumusdag, came in the wake of reports that Yildirim entered the referees' dressing room at half-time to issue a threat to the match officials of a Tranbzonspor game.
"He entered a room and said, 'Didn't you see those penalties?' which the referee said, 'I call what I see'. Then Yildirim responded, 'I will f**k what you see.'" Gumusdag is quoted as saying.
The trial for those implicated in the match-fixing scandal starts on February 14 2012. Yildirim remains in custody.
