The Pumas have stunned Ireland with a 43-20 win to book their place in the Rugby World Cup semi finals.

Two tries in each half helped Argentina prevail in a thrilling quarter final at Millennium Stadium on Sunday.

The Pumas led 20-3 after just 22 minutes to seemingly put the game to bed with an hour of the match still to play.

However, Ireland fought back to within just three points early in the second half, before tries from Joacquin Tuculet and Juan Imhoff sealed the win for Argentina.

Fly-half Nicolas Sanchez was outstanding kicking 23 points.

Argentina will face the winner of tomorrow's quarter final between Australia and Scotland.
