England were the only Six Nations team to see a change in their World Ranking position as they have let Argentina move above them. This has been a disaster of a tournament for England’s world ranking as they started the tournament in third. For the other teams, the implications of these results may be felt in the final week. Ireland and Wales traded no World Ranking points as they were too far separated, and Ireland were at home. Italy are now only 0.05 rankings and would move up to ninth in the world with a win over Wales next weekend.
