Kyrgios: "To win a Grand Slam".

Nick Kyrgios fears nothing.

While he's still preparing his return to competition, he recently opened up about his goals, and one thing's for sure: he's not thinking small.

The Australian declared: "I'm coming back because one thing keeps me in the game.

I've beaten almost everyone ahead of me in the rankings, reached Grand Slam finals, won doubles competitions, won numerous titles and made money.

But now, my goal is to win a Grand Slam. I think that's the only thing that will shut people up.

It will be a strong motivation."
