HAMBURG, Germany – U.S. shots at the World Cup have been scarcer than tickets.

The Americans have just one shot on goal in their first two games. Every other nation has at least four.

There’s been only one U.S. goal – scored when Italian defender Cristian Zaccardo knocked the ball into his own net.

Where’s the offense?

“It takes the opportunity. It takes the right mind-set. And sometimes it takes a bit of luck,” U.S. forward Brian McBride said Tuesday, two days before the Americans’ must-win match against Ghana.

If the Americans don’t beat Ghana, they’re goners, needing a victory and most likely an Italian win against the Czech Republic to advance.

McBride had a shiner under his left eye, the result of an Italian elbow in Saturday’s 1-1 tie. It was a vicious game, and he aged a year since then, turning 34 on Monday.

McBride is the only American to score in multiple World Cups, getting the team’s only goal in 1998, against Iran, and then connecting against Portugal and Mexico four years ago. He had a shot against the Azzurri, off a Landon Donovan pass, but sent the ball wide.

America’s lack of offense has been startling. According to FIFA’s statistics, the only shot on goal was Claudio Reyna’s drive off a post in the 28th minute against the Czech Republic. That’s by far the lowest total after two games for any of the tournament’s 32 teams. Angola is next-to-last with four.

“We’re getting the chances,” Donovan said. “A little unlucky. A little not sharp in front of the goal. But that’s the last thing I worry about.”

Taking any shots at all has been an issue. The Americans had 14 in their first two games, ahead of only Trinidad and Tobago (13), Iran and Poland (12 each), and Tunisia (10).

“We were facing some pretty good goalies in the first two games in Petr Cech and (Gianluigi) Buffon,” U.S. coach Bruce Arena said, “and I think when a shooter looks at the goal and he sees those goalies in there, their dimensions and their angles, you tend to be a little more precise instead of just hitting the frame.”

In other words, take a crack.

“Just get some shots on goal and test the keeper,” Arena said.

Donovan got goals against Poland and Mexico at the 2002 tournament, but has gone scoreless in 17 straight international games since July 9 against Canada. After disappearing for stretches in the 3-0 loss to the Czechs, he came alive against the Italians.

Arena wants to see more of that.

“I think Landon needs to get a little bit more aggressive,” Arena said. “The other day, Landon had played the one ball up to Brian, where maybe some other players continue to go to goal, take on the last guy and try to get a shot off.”

Under Arena, the United States adopted an offense far more flowing than allowed by his predecessors. He wanted to show that the Americans can play entertaining soccer, and they did in South Korea four years ago.
