Serena says she was 'nowhere near' Coco Gauff's level at 15

Serena Williams said that she was "nowhere near" as good as 15-year-old Coco Gauff when she was that age as the American great reached the Australian Open third round Wednesday despite being far from her best.

The 38-year-old, one short of Australian Margaret Court's all-time record of 24 Grand Slam titles, fought off a stubborn Tamara Zidansek 6-2, 6-3.

Williams faces China's 27th seed Wang Qiang next and could meet her fellow American Gauff in the quarter-finals in Melbourne.

The former world number one and Gauff -- touted as a possible long-term successor to Williams at the top of women's tennis -- spent some of the off-season together.

Williams, sporting a pair of koalas painted on her nails in light of the devastation of Australia's deadly bushfires, was mightily impressed by what she saw in "fighter" Gauff.

"She's just impressive all-round, from her personality to the way she plays," said Williams, the top-earning female athlete in the world.

"I think it's just all super-impressive.

"I was nowhere near her level at 15 either on the court or off the court, not even close.

"I know kids are growing up different nowadays, so I'm not sure. But I was nowhere near as smart and eloquent as she is.

"It's nice to see."
"She works hard on it, just gets unlucky sometimes health-wise obviously."
