Prior to 2000, each team played four matches, two at home and two away from home. Following the inclusion of Italy in 2000, each team plays five matches, two at home and three away in one year, and the opposite in the following season. When Wales won the Grand Slam in 2005, it was the first time that the feat had been achieved by a team that had played more matches away than at home. This was repeated by Ireland in 2009, by England in 2016, and by Wales in 2019.
