MIAMI, FEB. 1 -- Adrian Knup's last-minute goal, a volley from 14 yards that struck the underside of the crossbar and beat goalie Tony Meola, gave Switzerland a 1-0 victory over the U.S. national team tonight in the Miami Cup Soccer Tournament.

"This just shows we can't win a big game," fumed forward Bruce Murray, from Potomac, Md. "We have a lapse in concentration and we leave a guy wide open in the box. It can't happen."

Herbert Baumann earned the assist, sending the ball to Knup on a corner kick.

In their first official match of the year, several U.S. national players expressed discontent over Coach Bob Gansler's policy of trying out players inexperienced in top-flight international soccer.

"What happened shouldn't happen," said forward Peter Vermes. "We got a new team again. We've got to start all over again."

Four players -- Jeff Agoos of the University of Virginia, Jeff Baicher of Santa Clara University, Mark Santel of St. Louis University and Ronil Dufrene, who last played with a club team in France -- made their national team debut tonight. Murray, Desmond Armstrong and Vermes played on the U.S. team that played in the 1990 World Cup in Italy.

"It's a great opportunity for those new guys to get international competition," said Gansler. "On the goal, somebody just wasn't paying attention."

Said Armstrong, of Columbia, Md.: "Some are really starting to see the mental discipline you need to play on this level."

Switzerland Coach Uli Stielike praised Meola, who stopped several breakaways. "Tony Meola played a great match. He made a big save."

The best U.S. scoring opportunity came in the 68th minute when Vermes passed the ball to midfielder Chris Henderson, who then passed it to a wide-open Murray on the right side. Murray shot wide.

The United States on Sunday plays Germany's Bayern Munich, which tonight played to 0-0 tie with Colombia.
