All Blacks and Crusaders flanker Richie McCaw says that the Super Rugby title could be decided in one crucial moment in Sydney on Saturday.
The Crusaders are in their first Super Rugby final since 2011 when they lost in Brisbane to the Reds.
That 2011 Super Rugby final had it's own crucial moment when Will Genia make a dash for the tryline and scored a break away try.
"When it comes down to one or two moments, the teams that are good enough to take those opportunities are the ones that win," the All Blacks captain told AAP.
"If you drop your guard for one or two moments, you'll come second."
Saturday's Super Rugby final will be McCaw's eighth Super Rugby final appearance the first of which came in 2002 when the Crusaders won their fourth title.
Having played in seven Super Rugby final McCaw can remember several key moments that turned matches.
The last time the Crusaders won a Super Rugby final was in 2008 which ironically was against the Waratahs. In that match they thought they had scored a try but were called back for a punch thrown by Brad Thorn.
McCaw said that he could see the Waratahs got a lift from that moment.
"That was probably the moment that could have really cost us, but it didn't."
McCaw admitted that he is a little nervous ahead of the Super Rugby final despite all of his experience.
"Everyone says, 'y'know, you've got to go through the process of the week like you always do' and I think that's true," McCaw said.
"I think we've got to turn up on Saturday with all the detail of how we're going to play sorted."
"It's a good sort of nervous though," he said.
"These are the moments that you want to be involved in and the games you want to play in.
"You go through all the hard work for three or four, five months to give yourself a shot at this game."
The seven time champions have been through five years now without a Super Rugby title and they are desperate to avoid making it six years.
The All Black captain said that the current side are different to recent sides that have made it to the Semi-finals and then didn't perform.
"At least this year we've given ourselves a chance and now the big job is to perform when it really counts."
"That's what champion teams do, and that's what we're really keen to do."
