Donovan warns against complacency
Landon Donovan says USA's Group C encounter with Slovenia is "as big a game as we will ever play".
Lalas talks about USA and the World Cup
USA earned a 1-1 draw with England in their opener and victory on Friday would put them in a very strong position going into their final game against Algeria.
Donovan says the mood in the camp is very positive after the first match but, while he feels they are very capable of beating Slovenia, he knows there is no room for complacency.
"I think the England game solidified some beliefs we already had: that we can compete with teams of their calibre," he told FIFA. "We were left a little disappointed that we weren't better when we had chances to go forward but, the first game of a World Cup, against England, it was a great result for us.
"We're in a very good place right now. The bus ride home was a lot better after the draw against England. We are confident that Slovenia are a team that we can beat, and it's like a final for us.
"If we draw the game we are still alive, and if we lose the game it's highly unlikely we will advance, and we know if we win the game we are in a very good position, so this is as big a game as we will ever play. The guys are excited and ready for it."
He added: "The natural tendency after coming off that high is a lot of times a let-down. We have to make sure that doesn't happen.
"We talked all along about the importance of playing three games and, while there was a lot made of our game with England, we understand that this game is equally important. In some ways, it's more important because, if we lose this game, we are likely out of the tournament."
On a personal note, Donovan feels he will only improve as the tournament progresses.
"I feel good," he said. "Against England it was a little difficult because we didn't have much of the ball, so I didn't have a lot of time to make an impact offensively. I feel good about where I am going, and I feel like in the next two games I am going to get a lot better."
