Watch: Jamie Heaslip finishes off one of the greatest Irish tries of all-time
It couldn't have been a better first half from an Irish perspective, with the men in green running in four tries in a dominating opening period.
Encouragingly, the players seemed imbued with a new sense of freedom and the ball was played wide and offloaded in a manner that we haven't seen from the Ireland team in some time.
The pick of the tries came from Jamie Heaslip right on half time, with the number eight finishing off a glorious move that started with a Simon Zebo burst and saw Jared Payne, Johnny Sexton, Andrew Trimble and Fergus McFadden all get their hands on the ball.
That sumptuous score capped off an impressive half of rugby that also saw Trimble, Jack McGrath and CJ Stander also cross for tries.
