John Fogarty on challenge facing this Ireland team
Ahead of the game, this Saturday, assistant coach John Fogarty spoke about the challenges that await this Ireland team against the Springboks. He also spoke about the internal selection debates that will be raging on.
"We're clear in our heads as a [coaching] group," he told reporters. "We’ve no problem having difficult conversations.
"We're so lucky we’ve got such a good group of players – that’s something that Andy [Farrell, head coach] has developed. When he first came in, he was adamant we needed to develop a big squad, be competitive across the pitch.
"It's not easy to pick a side, we’ve got options. But that sharpens us as a coaching group and the players are going to be ready."
On the Springboks going with a 7:1 bench split [forwards to backs], John Fogarty said, "As a group of forwards, we’re incredibly fit and powerful, we've prepared for the weekend. It’s going to be a battle, one we feel the players will be ready for."
