USA midfielder Ricardo Clark is remaining cautious in the lead-up to next month's World Cup in South Africa.
The 27-year old Eintracht Frankfurt man hopes that the fans do not get carried away with the fact the national team are in a group they are expected to get out of as he believes that every opponent in the finals is a difficult one.
"I don't think we're on a par with the really big sides yet," Clark told FIFA.com. "Soccer is still growing in America. We still have a job to do and that's what we'll be focusing on over the next few weeks.
"People say we've been handed an easy group in England, Algeria and Slovenia, but there are no easy groups at the World Cup. Every game will be a challenge, but we can do it!"
Calrk added that he believes his own development since moving from the Houston Dynamo to Germany will add more to the national team in various areas.
"I've become a better player at Eintracht and I think that can help us at the World Cup. I can read the game well, especially from holding midfield, and I can also score goals," he added.
