The quest for back-to-back Under-20 Grand Slams gathered pace in Cork last night as reigning champions Ireland swept to a second consecutive bonus-point Six Nations victory.

Ireland U20s assistant coach Kieran Campbell expects his side to be more ruthless in tonight’s Six Nations second round clash with Wales at Musgrave Park (kick-off 7.15pm).

David McCann will captain the Ireland Under-20s as part of a 37-man Six Nations squad dominated by Leinster players.
