Brad Guzan has highlighted the magnitude of this year's Copa America Centenario for the USA.

The 2016 Copa America will be the first CONMEBOL tournament held outside of South America since the confederation was founded 100 years ago and the US has been invited to both host and compete.

US goalkeeper Guzan is well aware that the competition comes with an enormous challenge for he and his teammates but is also humbled that his nation gets to host a tournament so richly steeped in tradition.

"It's a huge opportunity on so many different levels," Aston Villa gloveman Guzan said of this summer's tournament.

"In terms of us as a team to play against great teams in a big tournament that means something, it's huge. For the sake of the country and US Soccer in terms of hosting such a big tournament, like I said, it's big on so many different levels.

"For us as a team and us as players, it's nice to be a part of something that's so widely known."

The US are drawn in Group A where they will take on Colombia, Costa Rica and Paraguay with their first match against the Colombians at Levi's Stadium in Santa Clara on June 3.
