In a recent interview with Toni Nadal for her regular podcast, Daniela Hantuchova asked what makes his nephew a great champion.
Uncle Toni, for so many years Rafael's coach, referred to the relentless work ethic and focus which was applied to whatever the younger Nadal was doing.
'I remember he put always big attention into hitting the ball, and he did the same with golf and football, which he also loved to play. He is very competitive, he loves to win,' explained Toni.
Daniela Hantuchova says Novak Djokovic and Rafael Nadal switching off aids their success
Following his 13th title at Roland Garros last month Nadal unwound by playing golf, at which he has a 0.3 handicap.
His build-up to this week's Paris Masters involved him coming sixth in the Balearic Golf Championship, from a field of sixty which was a mix of both professionals and amateurs.
Hantuchova, the former world number five who now works for Amazon Prime, has known both Nadal and Novak Djokovic, and their families, for a long time.
For her the ability of the two greatest male players to switch off is a key to the longevity of their remarkable success on the court.

'They've got a great balance in life and they know how to take their focus off tennis,' she says. 'That's what makes them so good. But when they come to the court it is all about tennis.
'And when you win so often, it's a feeling that you just want to keep repeating.'
Djokovic has absented himself from the last Masters event of this truncated season in the French capital, but plans to be in London in this month for the last event, the ATP Finals at the 02 Arena, which has survived UK government restrictions.
After contemplating cutting his season, Nadal has opted to play on by first returning to Paris, where only on October 11 he thrashed his greatest current rival to win Roland Garros yet again.
