Colombia have been in fine form in the tournament so far, topping their group and dispatching South Americans rivals Uruguay 2-0 in the Last 16 to secure their quarter-final berth.
“We are working hard to go as far as we can,” Armero said in an interview with FIFA.com.
“We knew from the very first game that it wasn’t going to be easy, and our approach is to take things one step at a time.
“We haven’t come here to enjoy ourselves but to give our all and go for glory.”
The Cafeteros next face another South American foe Brazil in the next round of knockout fixtures.
“It’s going to be a great game because both sides like to play good football,” said the Udinese defender, who insists the hosts are a strong side despite needing penalties to beat Chile in their last encounter.
“Brazil are not weak if you ask me,” the 27-year-old continued.
What’s happening is that all the teams want to go far, which is something we’ve been seeing since the World Cup started.
“Every team wants to win and they’re showing that. You also have to remember that Chile are a tough side with some great players.”
Armero highlighted Brazilian poster boy Neymar as the key man in the Selecao attack, and has called upon all his team mates to help out in ensuring that any danger posed by the 22-year-old in Fortaleza is easily dealt with.
“If we’re going to nullify the threat posed by Neymar, then everyone in the team will have to lend a helping hand to the players marking him,” he said.
The Colombian insists that the unity within their team has helped them achieve their good results so far in the tournament, which he hopes will continue for as long as possible in Brazil.
“We need to stick together and not lose our focus,” said Armero.
“We’re a compact side, and we know that when we all play for each other we tend to get results.”
Colombia’s match-up against Brazil is scheduled for 10pm South African time on Friday night.
