Carrick says they must buckle down in the remaining group qualifiers to make sure they are back in South America for the World Cup finals next summer.
"It's going to give us a taste of playing in Brazil," he said. "We've got a massive job to do, but it'll help us if we do get there next year.
"We have three home qualifiers [out of four] and we're confident we can win them. But we can't look too far ahead. The next friendly after Brazil is Scotland, and we'll focus on that, too."
