England v Wales
Ireland v Australia
Today sees the first double International Saturday of the season with Wales and England playing their first match in the Five Nations Championship and, in Dublin, Australia play the last Test of their tour.
The champions, Wales, travel to Twickenham intent on revenge for the 16 points to 12 defeat on their last visit while, for England, victory must mean a return of confidence and the hope that by the season's end they will have lifted themselves from the bottom of the table.
At Lansdowne Road, Ireland have had the advantage of having seen the Australians' tactics in the three previous Tests though, conversely, the Wallabies, after 12 weeks together, must know each other's play so well that it will take a very good side to upset them.
