Czechoslovakia reached the second round of the World Cup finals yesterday by beating its arch rival and neighbor, Austria, 1-0, in Florence.

A 30th-minute penalty kick by Michal Bilek was enough to give the Czechoslovaks four points from their first two games.

With one Group A match remaining for each team, Czechoslovakia and unbeaten Italy are assured of the top two qualifying places and will face each other for the honor of the top spot.

Austria must beat the United States by a huge score Tuesday to have any chance of gaining the final 16.

Czechoslovakia, which routed the United States, 5-1, in its opening game, took the initiative in the first half, showing its attacking skills at every opportunity.

On the penalty kick, Bilek coolly put the ball into the net after Austrian goalkeeper Klaus Lindenberger brought down midfielder Jozef Chovanec, who was carried off with an injury to his right leg. West Germany 5, United Arab Emirates 1: In Milan, tow goals by striker Rudi Voeller led the powerful German team to the easy win, qualifying it for the Cup's second round.

Voeller highlighted an attack that picked up where it left off in a 4-1 win over Yugoslavia in the West German's first game.

In all, West Germany had 23 shots on goal; the UAE had two. The crowd of more than 70,000 included thousands of Germans who chanted and loudly cheered the dominating performance.

"Our opponents were too quick for us," said UAE Coach Carlos Alberto Parreira.

Voeller broke through in the 35th minute, pushing home an assist from Klinsmann. Two minutes later, Klinsmann headed home a crossing pass from Stefan Reuter.
