HAMBURG, Germany — Changes are ahead for the U.S. soccer team.

The Americans played like tentative tourists in their opening 3-0 loss to the Czech Republic, and need a win against Italy on Saturday to revive their chances of reaching the World Cup's second round.

After reviewing video of the clunker several times, coach Bruce Arena alternated criticism of players with humor Tuesday as the Americans tried to shake off the defeat and start preparations for the Azzurri, a three-time World Cup champion.

Admitting that it was "very rare" to single out players publicly for poor play, Arena repeated his negative assessment of Landon Donovan.

"Landon's lack of aggressiveness in the attack, his running off the ball, his desire to make plays and be part of the game was not on last night," Arena said. "He knows that, and I'm sure he'll pick it up on Saturday."

He also challenged DaMarcus Beasley to accept his critical comments.

"If he's any kind of a player and a man, he understands that," Arena said.
