South Africa head into Friday night's Rugby World Cup Pool D match against Samoa knowing a bonus point will be enough to secure their passage through to the quarter finals.
The task for Manu Samoa is a lot trickier: they need to beat the Springboks, then hope Wales lose to Fiji on Sunday, or win with a bonus point and hope the Welsh fail to get one.
Springbok prop Jannie du Plessis admits he's a fan of the knockout-type atmosphere surrounding the match.
"All kinds of pressure is good at the end because if you want to go all the way you're going to be under extreme pressure so the earlier it comes, I think, the better. It is in a sense a knockout match for us so"
I think if you go into a game with that mindset it can just help you later on.
Samoan assistant coach Tom Coventry says they know they'll have to be at their absolute best.
If you want to stay in the tournament you win - we're well aware of that and where we sit in the frame of things. We'd hate to have to rely on bonus points if we're to get close and gain a point. There's other equations that work in our favour but first and foremost you have to win, don't you? Even if you are going to progress you probably are going to have to beat teams like South Africa to even consider yourself good enough to go ahead and get into the quarter finals/semi finals so we're under no illusion how big the task is that's for sure.
Meanwhile Samoan winger Alesana Tuilagi has been fined ten thousand dollars for wearing a branded mouthgard against Fiji.
