AC Milan defender Oguchi Onyewu says he knows what to expect from Slovenia's forwards when the two nations face off on Friday. Onyewu is aware that the eastern European players will work hard for each other to give their team every opportunity to score and insists they much be treated with caution.

But on the other hand, Onyewu said it was also important for the US players to concentrate on what they do best.

"They look like they're strikers that work for the team," he said. "They're hard workers, they run all across the field, they're going to do the dirty work in order for their team to come out on top. We're ready for that, it's nothing we haven't seen before. We just have to go out there on Friday and play the way we know how to play."
