HUGO KEENAN believes a fearless approach paved the way for Ireland to emphatically launch their Six Nations title charge with a devastating win which wrecked Warren Gatland’s return as Wales boss.

Full-back Keenan played a starring role on Saturday as the world’s top-ranked team subdued the Cardiff crowd by brushing aside the stunned hosts during a blistering start.

Tries from Caelan Doris, James Ryan and James Lowe helped build a commanding 27-3 half-time lead before Josh Van Der Flier crossed late on to crush Welsh resistance and secure a bonus point.
