Boks face different Kiwi challenge
Both Springbok assistant coach Johann van Graan and hooker Schalk Brits are well aware of the challenge that awaits them since Scotland have shown dramatic improvements under the guidance of New Zealand-born Cotter.
"They [Scotland] have been playing fantastic rugby and it will be a good Test match on Saturday. They have a forward pack that knows exactly what he [Cotter] wants.
"Scotland have tested us over the last four years in various parts of the world. They have got some world class players and they bring different challenges in the way they defend and attack. It's definitely a different challenge to Samoa but it remains a massive challenge," van Graan said.
Brits expressed that he enjoys watching Scotland play and that Cotter's Kiwi influence is clear for everyone to see.
"Without a doubt it's his New Zealand influence and he has a few New Zealanders playing in his setup. You can see the pattern moving from Clermont to Scotland and it will always take a while to change game patterns and change certain players to play his style and it is paying off at the right time for them.
"I actually like watching them. Cotter wants his players to play with discipline but still allows them the freedom to play. It's great to see Scotland being strong, you want everyone to be strong because it makes the game better for all of us and this weekend will be a great showing.
"It's our 'final' because if we lose this one then we are out. We are in this position and we are ready to fight and make our country proud. It's going to be exciting to see two good teams having a proper go at each other," Brits said.
Other than a Kiwi coach, the Scots have some South African flavour in their squad with the likes of forwards Josh Strauss and WP Nel in their ranks and Springbok loose forward Schalk Burger believes that will throw a spanner in the works of using Afrikaans during the game.
"He [Josh Strauss] is difficult to play against and he understands Afrikaans, so we can't come up with some plans.
"He is an outstanding player and was with us at WP for about three years in his junior years before he moved to the Lions and played unbelievable rugby there. He is a strong carrier and a typical South African flank, an honest player who puts his hand up when it's needed by the team and doesn't give up," Burger said.
There was one other attributed to Strauss' game that Burger feels is the hardest part about him.
"The hardest part of playing against him is his beard, its tough to get around it to tackle him," Burger added.
