The Turkey midfielder's contract negotiations have been dragging on for months, with a major difference between Yildiz's current €6m-a-year demands and Juve's last offer of €4.5m-a-year.
"I'm not talking about my contract," he said after the 2-0 win.
"I'm only focused on the pitch and what I have to do here. I'm happy at Juventus, and that's what matters now."
On working with coach Luciano Spalletti, Yildiz also told TRT Spor: “He said he loves me like a son. I feel great at Juventus; this is my team. I have a special relationship with the coach: he's a great person, he does so much for me, and I always try to give everything for him and the team.
"The enthusiasm of the fans is incredible. When I'm with the fans, I feel a great emotion. I see my shirts, I sign autographs, I try to stop by whenever I can. They are very important to us and to me personally.”
