Spaniard Rafael Nadal insists he is still confident of winning major titles, with retirement currently not on his mind.
The former world number one spent most of the 2016 campaign struggling with injury and slipped down the world rankings.
He is just clinging onto 10th spot ahead of the Australian Open but will need to perform in Melbourne, with the tournament set to get under way on January 16.
Nadal did manage to make the quarter-finals of last week's Brisbane International and the 30-year-old is adamant he can still compete at the highest level.
"If I believed that if [I] could not have this chance during this next 11 months, I would be home fishing," he told reporters in Sydney.
"My real goal is to try to compete for the important things and to compete for the important things I know I have to try to beat [Novak Djokovic and Andy Murray].
"If I am working hard and I have the motivation and passion to keep going, I feel that if I am happy and I can work the way I want to be, I can be."
