Argentina deserve their pre-World Cup ranking of fifth says Wales fly-half James Hook, singling out rival Felipe Contepomi as the man Wales must stop.
James Hook is relishing his battle with Felipe Contepomi on Saturday
Speaking ahead of Saturday's warm-up game at the Millennium Stadium, Hook highlighted the threat of experienced Contepomi.
"He's a great player and if we can keep him under wraps a bit, we'll be all right," said Hook.
But he warned Wales' forwards needed to match the Pumas' renowned muscle.
They deserve to be where they are and it's going to be a tough game
"If things are going well for them up front, they won't need to use the good players they have behind the scrum," 22-year-old Hook added.
Wales, eighth place in the International Rugby Board rankings, are licking their wounds after a record 62-5 defeat against England on 4 August.
Meanwhile Argentina are being touted as dark horses in next month's World Cup in France, and Hook said their recently-gained fifth-place world ranking was deserved.
"They have a great pack and some great individuals in their back line.
"They deserve to be where they are and it's going to be a tough game on Saturday."
Hook said he had good memories of playing against Argentina, having scored a try on his debut on tour there last summer.
Contepomi meanwhile is full of praise for the Welsh claiming that people shouldn't judge Gareth Jenkins' men on their record 62-5 defeat to England.
