Paraguay opened their World Cup Group F campaign by drawing with world champions Italy after showing their mettle on the way to South Africa by beating their two illustrious neighbours in the qualifiers.
"The true motivation is to play and to defend the colours of our country," defender Claudio Morel told a news conference on the eve of the match.
"I don't know if we are in the shadow of Argentina and Brazil but we are here to compete against these teams on an equal footing."
A small country of six million people, Paraguay's violent history has also bred a tenacity and patriotic spirit that serves its footballers well.
"It is difficult to satisfy the people, they have dreams, we want the country to be with us, we don't want to disappoint the country," said coach Gerardo Martino, an Argentine who made his name in Paraguayan club football before taking the national job.
The "Albiroja" will be especially wary of being caught on the counter-attack by the Slovaks.
"I guess we all watch out for our opponents, the only responsibility we have is to qualify, it doesn't matter when it comes or who against," Martino said.
