Caroline Wozniacki insists she has nothing to prove despite a disappointing 2015 that saw her win just one title.
The Dane dropped down to 17th in the rankings as she finished with a 39-23 record on the WTA Tour, only tasting success in Kuala Lumpur in March.
After a strong finish to 2014 that saw Wozniacki reach the US Open final and last four of the WTA Tour Finals - where she was beaten by Serena Williams on both occasions - much was expected of the resurgent 25-year-old.
However, she failed to build on that promise and her performances in the grand slams - where making the fourth round of Wimbledon was her best result - saw the former world number slip to her lowest year-end ranking since 2004.
"I don't feel like I have to prove anything to anyone," she told TV2 Sport. "I have been the best player in the world and I have won many tournaments.
"It's obvious that every time I step on court my goal is to win. Next year five important tournaments [four slams and the Olympics] will be played and I hope I can give my best."
She added: "I think the crowd is used to see me winning, to see me on top, and I believe it's positive that people consider me as one of the best players in the world. I do it too.
"Even when I am injured or when I have some struggles I don't give up. I know I am one of the best."
