Australian heavyweight boxer Solomon Haumono has labelled Sonny Bill Williams as a soft target and challenged former world champion Danny Green to fight him instead.

Green who is a four‑time world champion in the super‑middleweight, light‑heavyweight and cruiserweight divisions wants to fight Sonny Bill Williams next year.

Green retired in 2012.

Sonny Bill Williams has not been in a boxing ring since January when he won his seventh fight.
