#3. Billy Vunipola to Tonga or Australia
The 29-year-old, born in Sydney in 1992, would be free to play for the Aussies when he completes his three-years stand down from international rugby.
Winning 61 caps since making his debut in 2013, reports down under suggested Aussie chiefs wanted to make contact with the powerhouse about a potential swap prior to his recall last Autumn.
Tonga, who Billy’s Dad Fe’ao played for in the 1990s, also remain keen on the Saracens star.
