The IRB's head of development and performance, Mark Egan, says the gap between the tier-one and tier-two nations has closed significantly.

After a first round of matches that Martin Johnson described as "perhaps the greatest ever", the points differential between the leading and developing nations has halved since the last World Cup.

Egan talks about what the IRB is doing to ensure the gap continues to close, including news of tier-two unions playing in the November internationals next year and that tier-one countries will be involved in some new tour schedules over the next few years.
