The conflict between club and country, leagues and Tests, has never been more intense. European super clubs now rival the depth and skills of national sides, but the vast majority of fan interest and financial support remains with Test rugby. The Six Nations stands out as the most successful annual tournament in rugby due to the depth of its rivalries, straightforward design, and the close proximity of its fan bases. Nowadays, it is the Irish and French teams that bring many of the new ideas to the table. It remains a compelling spectacle despite the fact that the tournament rarely produces the world champion.
