Gotze admits seeing Nuri Sahin at Real has sparked his ambition.
"My future? I'm very happy where I am. But you never know: Sahin also was settled here and now? Now he's playing at the Bernabeu," said Gotze.
"(Mesut) Özil and (Sami) Khedira are two players that make me most excited to play for Germany, because they are players of Madrid.
"It's special to play with them."
