The 19-year-old is having a breakout season in the Bundesliga with Hamburg, starting all 25 of his league games and popping up with five goals.
As a result, Vuskovic has been linked with several top European sides, including Bayern Munich, Barcelona, Real Madrid, and Chelsea.
Speaking to German outlet Frankfurter Allgemeine Zeitung, about his future, the defender kept his cards close to his chest.
"In football, you never know," Vuskovic said.
"It could happen next year, or in 10 years. I don't want to promise anyone anything. After this season, I'll be a Tottenham player again. I have a contract there until 2030."
Vuskovic is yet to play a competitive game for Premier League strugglers Tottenham.
