Sonny Bill Williams has all of the skills needed to be a successful coach in rugby league, according to current Sydney Roosters boss Trent Robinson.
After a glittered career in both rugby league and union, Williams this week confirmed he's hanging up his boots with the intention to return to boxing, although will take up a mentorship role with the Roosters.
Highly regarded by the Sydney club, coach Trent Robertson told AAP that the former cross-code star had everything needed to succeed in the coaches box.
"He's definitely got the tools to be a coach," Robinson says.
"He's got presence and game understanding and a real depth as well and intuition in the game.
"It's whether he is going to overlay that in the work needed to strip it all back and understand the art of coaching, which takes a bit of time.
"Passion has been a driver for him for many years.
"Seeing where that passion lies for the next few years will be really interesting for us and him."
The 35-year-old spent two stints with the Roosters, lifting the NRL premiership in 2013, as well as having won his maiden title with the Bulldogs in 2004.
Williams' success wasn't limited to the 13-man code either, winning two Rugby World Cups in 2011 and 2015, and consecutive Super Rugby titles with the Chiefs in 2012 and 2013.
