The controversial star is set to make his Grand Slam return at the Australian Open following a serious wrist injury that ruled him out for two years and thinks his comeback is "important" for the sport.

Kyrgios said: "We watch sport because we want personalities.

"For me, being personally back, I think it adds a bit of question marks to what is going to happen today. I love that. Every time I step out on court, I don’t know if I’m going to be super controversial in a good or bad way."

The former Wimbledon finalist has been a divisive figure during his career but he believes that he adds a sense of "excitement" to the tour.

Kyrgios said: "Throughout my career, it hasn’t always been good, but it’s added a lot of excitement to the game.

"I think it’s important. There’s so many good players on the tour now. I think there’s not so many contrasting personalities.

"I think it’s healthy that I’m back and I’m playing. Doesn’t really weigh on me, though. I’ve always been someone that’s played my brand of tennis, and I guess my personality, I haven’t changed since I was 10 years old.

"I think it’s good to be back. I think it’s important. I think the sport was getting a bit mundane."

There have been question marks as to whether Kyrgios will play in Melbourne after suffering an abdominal strain and discomfort in his wrist on his return to competitive at the Brisbane International and the player says he is "taking it day by day" before making a decision on his fitness.

The Australian ace said: "This morning I was out there feeling pretty good. I still have three days before the tournament starts for me."
