Justin Marshall - former All Blacks halfback and current rugby commentator for Sky Sport - joins Martin Devlin on It's Only Sport, looking ahead to the first test between New Zealand and South Africa in 2024. The Springboks will host their old rivals in Johannesburg in a repeat of last year's Rugby World Cup final in Paris, which the Boks won 12-11. Marshall talks to Devlin about what it's like playing in South Africa (specifically at Ellis Park), his confidence levels in New Zealand getting a result in the first test, and selections he would like to see All Blacks coach Scott Robertson make for what will be a physically demanding contest. The two also talk about Leon MacDonald's shock departure as one of Robertson's lead assistant coaches.
