A VICTORY over South Korea's Chung Hyeon 7-5 6-3 in the second round of the Paris Masters has ensured Rafael Nadal ends the season on top of the ATP rankings.
Nadal set up a third-round clash with Uruguay's Pablo Cuevas and said his focus was winning the Paris tournament for the first time and not being No.1 in the world.
"It was not the goal," Nadal said about finishing the year as number one.
"It was impossible for me to think about that when you are coming back from a tough period of time without playing tennis and with so many injuries in the last couple of years.
"But it happened and I'm very happy of course.
"After almost 10 years since the first time that I finished the year with this number. So I think it's a very important achievement."
Earlier, Germany's Alexander Zverev was knocked out in the second round 3-6 6-2 6-2 by Dutch journeyman Robin Haase.
Jo-Wilfried Tsonga's hopes of taking part in the season-ending Tour finals in London went up in smoke as he lost 2-6 7-6(4) 6-2 to fellow Frenchman Julien Benneteau.
