Sonny Bill Williams has admitted that this Friday's Super Rugby Semi-final could be his last match for the Chiefs so he is hoping his team will play "better than we ever have".
Williams (SBW) has agreed to leave the Chiefs after the Super Rugby season and play rugby in Japan so unless the Chiefs make this final next week this match will be his last in New Zealand Rugby for some time.
If the Stormers and the Chiefs win their matches this Friday's match will be Williams' last on New Zealand soil.
"I don't want to get too emotionally attached to it, because it could be my last week here, but I'm just trying to turn all those emotions into motivation," Williams told Fairfax.
"I want to come in, do all my work and try and build like I haven't done it before - try and tick all those boxes.
"And then hopefully run out there on Friday night fizzing and just do my role really well."
Williams has experienced big pressure matches on a few occasions through his career and instead of allowing the emotion get the better of him he wants to use it to bring out his best performance.
Aside from playing for the Crusaders who reached the Super Rugby final last year he also played in last year's Rugby World Cup for the All Blacks and also won a NRL title with the Canterbury Bulldogs in 2004 so he knows something about big matches.
"You've still got to do what you do, keep it simple and nail everything you do during the week so you're confident.
"That's probably what I will do. Just nail everything that I usually do and go into the game knowing I've done everything I can, then just play footy and back myself."
Williams has predicted that the Semi-final will be a big step up from any other match that the Chiefs have played all year including the match when they played the Crusaders two weeks ago.
"You've just got to be at your best and in those times when you're in that dark place that's when you use it as well to try and pull something out, keep pushing hard, keep getting up off the deck and making that extra tackle - just things like that," he said.
Williams says that the New Zealand Conference winning Chiefs have every reason to go into the match believing they can win.
"Be confident, we deserve to be here and we've just got to play footy."
"But in saying that it's a lot of hard work. "
"The Crusaders have got internationals all over the field and are in really good form so we're going to have play better than we ever have."
Williams added that the Chiefs have also had the benefit of an extra week of training and time off to shake off any niggling injuries.
"We've got a whole week of extra training in, working those combinations, and we'll take that onto the pitch on Friday," Williams said.
Williams said that the Chiefs backs will need to take every opportunity that comes their way and finish it off and not make mistakes like the one he did at the end of the last match between the teams.
"Just being on our toes and taking every opportunity and making every opportunity count. "
"That's something we haven't done in the last couple of weeks and that started against the Crusaders in that last five minutes when I didn't pass the ball when we had a two-man overlap.
"Just little things like that have crept into our game I guess and that's why it's been good to have these two weeks to assess ourselves and now know what we have to do."
