Nick Kyrgios's 2016 ended with a tour ban but Rafael Nadal believes the 21-year- old Australian can turn it all around and that 2017 will see him continue to rise.
Kyrgios's effortless 6-3 6-1 defeat, suffered at the hands of German journeyman Mischa Zverev resulted in an ATP Tour suspension that saw the Australian apologise for his actions.
It was also a 2016 that saw Kyrgios rise to a career-high ranking of No.13 in the world and Nadal says there is more to come for the prodigiously talented Aussie.
"Kyrgios is already at the top. (He is) a player who has an unbelievable potential. He has focus on himself, and can become world No. 1 and win a grand slam," Nadal told News Corp Australia.
Nadal, also feels that if fellow Australian young gun Thanasi Kokkinakis can return to the court and put his injury issues behind him, he too has the game to succeed at the highest level.
