The Millennium Stadium pitch cut up badly in the first Test with New Zealand
Wales hooker Matthew Rees has welcomed the decision to replace the Millennium Stadium pitch before Saturday's match against Argentina in Cardiff.
A fly infestation weakened the grass roots and the pitch did not wear well in games with New Zealand and Samoa.
A firm footing will be crucial with the Pumas fielding a hard-scrummaging pack.
"It's been embarrassing the last two games really, the pitch chewing up as much as it has been, so hopefully this weekend it'll be fixed," Rees said.
Wales coach Warren Gatland has kept faith with Paul James at tight-head prop, the Ospreys loose-head acquitting himself well in the unfamiliar number three jersey.
Rees, James and Gethin Jenkins are tasked with holding their own against one of world rugby's most established and formidable front rows in Argentina's Rodrigo Roncero, Mario Ledesma and Martin Scelzo.
"It is new for Paul but what better opportunity to stake his claim by playing against one of the best scrummaging sides in the world and I think he's looking forward to the challenge as well," Rees said.
"The [Pumas] front row, they've played together for a number of years now and it's great to play against them again.
Gatland tells Wales to 'get smart'
"We know it's going to be a physical game again, it's going to be tough up front.
"They've been known for their scrummaging, Argentina, obviously a lot of them are France-based and spend a lot of time scrummaging.
"So it's something they'll probably come at us with and we need to be ready for that."
Despite missing players of the calibre of Felipe Contepomi, Juan Martin Hernandez and Juan Manuel Leguizamon through injury, Argentina only lost 16-9 to England last weekend thanks to Matt Banahan's late try.
"From the game at the weekend against England they were unlucky to come away with a loss," Rees said.
"It's going to be a difficult challenge for us on the weekend but something we are looking forward to.
"No matter who's playing for Argentina they're going to be a formidable side anyway.
"We need to take one game at a time now, we know how important this game is to us.
"Obviously playing Argentina at home is going to be huge."
