DUBLIN - As Ireland look to wrap up a second Six Nations title in a row on Saturday, a further sign of the potential sustained success to come will be on display the night before when the country's next generation aim to go one better.

The under-20 team's bid for a third successive Six Nations in a race that is going down to the wire is part of an unbeaten run in the competition that stretches back almost three years and includes two Grand Slams.
