Sonny Bill Williams 'a training freak' as he completes his first traininig with Toronto Wolfpack

Former All Blacks star, Sonny Bill Williams has been hailed as "a training freak" after completing his first practice with the Toronto Wolfpack ahead of his return to rugby league.

Williams who has won two Rugby World Cups and is a former NRL superstar, joined his new team mates at the transatlantic rugby league team's training base in Manchester, England.

Toronto Woflpack coach, Brian McDermott says Williams has come back in great shape and the guy is a gym freak.

McDermott says they cannot keep him out of the gym and he looks good.

Williams joined the Wolfpack a few days after their third-place finish in the 2019 Rugby World Cup in Japan last November.
