OVER the next two seasons Warrington Wolves will square up with a Sonny Bill Williams who believes Toronto Wolfpack's style of play will get the best out of him.

The 34-year-old faced the media for the first time since his fifth switch of codes between rugby league and rugby union, signing a two-year contract with the Canadian club in a deal thought to be worth in excess of £5million.

Williams, a dual-code international, had a lengthy meeting with Toronto head coach Brian McDermott after appearing in the All Blacks' loss to England in the rugby union world cup semi-final in Japan, where he was convinced to sign up to the Wolfpack project.

The two-time world cup winner, who last played rugby league in the NRL five years ago, believes Toronto's style of play will suit him, adding: "After I spoke to Brian, I started watching a few of their games.

"I could tell straight away their style is different to other teams and then I made contact with a couple of the Australian players and by all accounts it's different and there are challenges, but I've always had challenges in my journey, so this is nothing I'm not used to.

"Overall what they're trying to achieve on and off the field is something special and instead of looking at the challenge and thinking what if I fail, it's what if we succeed and I am part of that.

"North America, if that door opens? The opportunities for young players coming through would be amazing for themselves and their families and to say I am a part of that would be something special."

Prior to the World Cup in Japan, the All Blacks centre had intended to remain in New Zealand, but this gave him a new challenge to get stuck into.

"Once this opportunity come about. It was an opportunity I couldn't turn down," admitted Williams, who famously bombed a try for New Zealand against Samoa in a 2013 Rugby League World Cup game at The Halliwell Jones Stadium by losing his footing and slipping over the dead-ball line.

"Yes, I'm a sportsman but I need to have a purpose and something that I really believe in," he said.

"Just Brian's philosophy and how he wants to play the game, I feel like I can be really suited to their style of play.

"As Toronto players, we are going out there to turn some heads, but also the amount of support the lads have back in Toronto sounds crazy. It is a journey, there is pressure there, but it's so exciting."

McDermott, who coached Leeds Rhinos to Grand Final, Challenge Cup and League Leaders' Shield glories, believes the signing of Williams will help people around the world take notice of Super League.

Williams is understood to be the highest-paid player in the history of both rugby union and rugby league but has a global following.

McDermott spent seven years coaching Leeds before he took charge of Toronto and says Williams will help put the sport on the map in a global sense.

He said: "Leeds are a big club, Wigan and St Helens are big clubs, and Warrington and the two Hulls are big clubs in Super League, and if anything happens for them, it's big in Super League, but it's not big around the world.

"I don't think any millionaire, billionaire or major investor is going to get involved with a club on a significant level or anyone who wants to get involved in the sport is going to get excited because Salford might win a Grand Final or Featherstone could win the division below.

"Within the sport that is brilliant, but that is not exciting too many people around the world and what Toronto are doing, is making people around the world take note of Super League."

Although part of the reason the Wolfpack wanted to sign Williams is the brand that comes with him, McDermott insisted he will become one of the best players in Super League.

He warned it would take the dual-code international time to get up to speed and predicted the Canadian club would not see the best of him until the final third of the year but knows he will not buckle under the pressure.

McDermott added: "There were a billion eyeballs on the semi-final of the World Cup and I don't know what the figures would be, but how many people are now clicking on one of the biggest rugby union players in the world and seeing where he has gone to.

"They will follow where he has gone to and they may have no interest to start with about Super League or the Wolfpack, but they are now going to do that.

"I completely get why our owner David (Argyle) wants to sign Sonny Bill Williams. If Sonny Bill was an OK player, he would be happy, but he is going to use - and is paying for - Sonny's brand and everyone is cool with that and it works.

"That is why I went out to Japan. I needed to make sure he wants to be one of the best players in the league, which from our conversations will be the case."
