Williams keen to test himself against the best

It has been an important week in Williams’ rugby career, arriving in Dublin with the Wales squad after agreeing a new two-year contract at the Scarlets.
But ahead of him is a head-to-head with Ireland midfield talisman Brian O’Driscoll as Wales target an 11th victory from the last 12 RBS 6 Nations starts. Wales are also aiming to preserve an unbeaten tournament away record that has been in place for almost two years.
