As Namibia prepare for their final match of the 2015 Rugby World Cup against Argentina, stand-in captain Rohan Kitshoff has issued a rallying cry for his team-mates to depart the tournament by leaving a lasting impression.

The minnows have toiled throughout their Pool C campaign, with just a bonus point from their 17-16 defeat to Georgia to show for their efforts.

The national team are still awaiting their first World Cup victory, after 18 unsuccessful attempts, and have conceded 60 points on each of their two meetings with Argentina.

Namibia will be without regular captain Jacques Burger, who suffered a concussion against Georgia and subsequently announced his retirement, but his deputy Kitshoff is insistent his men can spring an upset on a Pumas side whose quarter-final place is already assured.

"We are still striving for that win and because we are a team of strong character we won't look at where they are and where we are in the rankings," he said.

"It's the 80 minutes on the field that counts. Now we are looking forward to Argentina. It's one last shot for us to really show the public, and prove to ourselves, that we are good enough to compete at this level.

"In the past, the World Cup has been the epitome of a four-year journey. But what changed this time round is that this is the start of the next four-year journey.

"That's what's so great about the selection process as well, that everyone gets a chance to play and get that experience. If you get that experience it carries into the next four years and it is a very healthy status.

"It's important to leave the impression to world rugby that Namibian rugby is on the up."

Both sides made 11 changes to their starting XVs for Sunday's clash at the King Power Stadium, with the Pumas' place in the last eight confirmed by New Zealand's 47-9 hammering of Tonga on Friday.

Juan Pablo Socino makes his World Cup debut in the centre for the Pumas, who have named their youngest and most inexperienced starting World Cup XV since a clash with Samoa back in 1999.

Regardless of Sunday's result, Argentina will finish second in the pool and will take on the victor of the final Pool D showdown between Ireland and France in the last eight.
