Sonny Bill Williams sons don't want to play for New Zealand

"Cape Town is my second home," said Williams, who married South African model Alana Raffie in 2013.

"Maybe one day my two boys might be playing in Green and Gold. They've told me that's what they'd like.

"They love the Springboks."

South Africa want to join the Six Nations in the near future.

Below, we look at five other rugby legends sons who are making waves, but currently want to represent different countries to their legendary Fathers.

This list includes Dhyreille Jonah Lomu, who dreams of playing in the Six Nations

Brooke, who can play across the back-row or at hooker, grew up in England so is fully qualified to wear the red rose. The powerhouse has represented Berkshire at county level and regularly played for his school, Wellington College. Brooke has also played on the international stage with England U20.

Vunipola comes from vintage rugby stock and is already well on his way to following in the footsteps of cousins Billy and Mako as part of the England U20s set-up. His dad, Elisi Vunipola, played in Super Rugby for the Brumbies, as well as appearing 41 times for Tonga – including at the 1995 and 1999 Rugby World Cups – and was his country’s most-capped player upon retirement in 2005.

Dhyreille Jonah Lomu, who currently plays on the wing, was born in France during his Dad's brief stint playing for Marseille, hence any eligibility discussions wouldn't be an issue.

Known as 'Frenchie' at school in New Zealand, the aspiring youngster has already began to impress at a number of age-grade tournaments in New Zealand.

The surname Umaga carries a lot of weight in rugby. Mike Umaga won 13 caps for Samoa, while Tana is one of the All Blacks’ most respected captains. And it appears the name could live on with Jacob, son of Mike and nephew of Tana, who is seen as one for the future for England after being called up on multiple occasions by Eddie Jones.
