The Eagles’s first match at the tournament comes against the 2014 winners, who have played more T20 World Cup matches than any other team.
And that is why Erasmus says Namibia have nothing to lose and everything to gain in Abu Dhabi.
“I think most definitely the pressure is on them to win,” said the 26-year-old.
“We are going in there with a permanent underdog tag and that is always nice, makes us nice and free.
“Maybe they are a bit under pressure because of recent results and that puts a team up for the taking, and if we do it well, we can take them down.
“We’ve played lots of T20 cricket against high-quality opposition, and we have travelled a bit so we are accustomed to playing in different conditions, playing against different skills.
“I am more than happy with our prep and if we can bring it together for these three games, I am confident we can go through.”
As Namibia makes its T20 World Cup debut, coach Pierre de Bruyn explained how the occasion is not lost on his players.
“It’s been a long wait and the players can’t wait to get going,” he said.
