New Ireland captain Jamie Heaslip has braced his team-mates for a bruising collision with South Africa in Dublin tomorrow (Live on RTÉ Two and www.RTÉ.ie/sport, from 5.00pm).
Ireland have won three of their past four meetings with the Springboks, but the most recent encounter was a 23-21 defeat in the opening game at the Aviva Stadium.
Five of Heaslip's 53 caps have come against South Africa, including three Test appearances for the Lions, and he knows what to expect.
"South Africa are a very confrontational side and they don't make any bones about that," he said.
"They try to run over you or through you with their forward pack and provide nice ball for their backs to run around you.
"You can't afford to give away any penalties because of the kickers they have. They are clinical.
"They got one over us last time and we don't like losing in our back garden. It will be a full house on Saturday and the place will be rocking.
"We want to give the Irish people something to cheer about."
