We are now heading into the closing stages of The Rugby Championship, and all four teams can still win it.
It was a Test match for the ages on Thursday, as the All Blacks picked up a hugely controversial win against Australia. That game has more than set the tone for another huge clash in the tournament.
South Africa head into this clash unaltered, whilst Cheika has reigned in the changes following Los Pumas' battering at the hands of the Kiwis last time out.

What have the coaches said?
Argentina head coach Michael Cheika: "When we got back to work at the start of the week, everyone had a good attitude, very positive and have concentrated on the strategy for the game".
"It will be important to impose our way of playing. South Africa are a lot different to play against than Australia and New Zealand. It will be a different dynamic."
South Africa head coach Jacques Nienaber speaking on the Elton Jantjies debacle: "I've said before that there's a lot of pressure any national team has to deal with. There are two types. One is external pressure. Can we control that? No.
"There's internal pressure, the type where we demand certain standards from each other. It's about expectations. That's the pressure we can control"
"Internal pressure is what we focus on. External pressure, be it injuries or even speculation, is something we have to brush aside because we can't control it. It's no use expending energy on it. We can't change it. It is what it is."
