PARIS, Oct 11 (Reuters) - France will need to increase their intensity to match the physical challenge posed by South Africa in Sunday's Rugby World Cup quarter-final, eighthman Gregory Alldritt said on Wednesday. It's up to us to put in more intensity than usual for 80 minutes," Alldritt told a press conference. "As we saw in Marseille last year they're a team that stays in the game for 80 minutes. One of the key battle in the game will be that between the loose forwards and Alldritt praised the opposing trio. "I think they're a reflection of the team, a back row that gives a lot in defence and attack for 80 minutes.
