The German international, whose current terms expire in 2016, has been linked with penning a bumper new deal at the Santiago Bernabeu.
"It's nice that Madrid want to renew," Ozil told Sport Bild. "It makes me happy because it is a sign of trust in my performances.
"But, at the moment, there is nothing decided and there is no pressure. Of course I can imagine finishing my career at Madrid, but I can also imagine doing something completely different at some point."
Ozil joined Madrid from Werder Bremen in 2010.
