Brian O'Driscoll: We need a lot going for us but I’m still a believer

Brian O’Driscoll believes Ireland can back up their World No.1 ranking by winning the Rugby World Cup in Japan. The 133-times capped centre says the ranking is ‘nice’ – but lifting the Webb Ellis Cup is the be all and end all for Joe Schmidt’s men.

Ireland’s win over Wales in Dublin lifted them to the top of the World Rugby rankings for the first time, leapfrogging World Cup favourites New Zealand.
