PARIS (Reuters) - Ireland must remain calm after edging defending world champions South Africa, captain Johnny Sexton said on Saturday as he lauded his team's resilience and the "insane" support of thousands of green-clad fans that lifted them in tense moments.
Top-ranked Ireland claimed a 13-8 statement victory over the Springboks in a high-octane heavyweight World Cup clash that lived up to the hype at a sweltering Stade de France.
