Ireland round off their autumn against world champions South Africa, who Conan says are “deservedly the best in the world”.
After winning the Rugby Championship, the Springboks have won all three of their November matches in the northern hemisphere and will look to claim a tour clean sweep in Dublin after wins over Japan at Wembley, France and Italy.
Ireland famously stunned South Africa in the group stages of the 2023 World Cup before the Springboks rallied to win the tournament, and the sides drew a summer series in 2024.
“They are a good team, aren’t they?” Conan said.
“You can see what they are doing with the bench and how they apply their forwards.
“They are changing the game and it is great to see. It’s innovation, it’s interesting and it’s getting eyeballs on the game.”
The biggest concern for the Springboks has been discipline in their last two matches. Lood de Jager was sent off for a reckless tackle against France, and Franco Mostert was dismissed on Saturday against the Italians.
Despite being a man down for the majority of both matches, Rassie Erasmus’ side came through to win both times.
“They are going really well. They were probably disappointed with their red cards over the last few weeks but they are an unbelievably physical side and deservedly the best in the world,” Leinster back row Conan added.
“They will be a huge challenge for us and we love a challenge. We love having to be better.
“It’s probably never been as enjoyable to play for Ireland as it has been right now.”
