Rugby World Cup 2015: Ireland's Cian Healy preparing for scrum battle

Prop Cian Healy says Ireland's forwards have "pushed themselves to the extreme in scrummage training" ahead of the anticipated battle up front against Argentina in Sunday's World Cup quarter-final.

The Leinster front-rower, who is relishing the confrontation after a lengthy spell out injured, is pleased Johnny Sexton has been deemed fit enough to start in Cardiff.

"Johnny is a big leader for us and controls a lot of our gameplan," said Healy.
