Argentina is a dog with size and fight

Ronan O’Gara looks forward to what promises to be an exciting weekend of rugby action and warns that Ireland should not underestimate Argentina who, he suggests, are playing better than ever before.

Let’s make no bones about this, Argentina are a good team. Ireland’s quarter-final opponents are playing at a tempo the Pumas have never played before.

You want to be facing a big dog or a terrier that just won’t let go? How about a crossbreed? That’s what is staring across the halfway line at Ireland on Sunday.
