Nallet awaits 'effective' Ireland

France lock Lionel Nallet has warned Les Bleus to be on their guard against Ireland this weekend – but has not been overly gushing in his analysis of Declan Kidney’s Grand Slam champions.

Marc Lievremont’s team started their RBS 6 Nations campaign with a comfortable 18-9 win over Scotland at Murrayfield last Sunday but can expect a sterner test of their title credentials when the Irish visit the Stade de France on Saturday.
