"The final decision will come in early May," Klinsmann told Monday's edition of Kicker magazine. "I myself still don't know who will be in goal. We make decisions as a team and the decisive question is what is best for the team." 

Klinsmann has been alternating between Bayern Munich's Oliver Kahn and Arsenal's Jens Lehmann, and critics have urged the coach to make an early decision ahead of the June 9-July 9 tournament.

But Klinsmann says the possibility of injury makes it necessary to delay his selection.

"We know that when we announce the decision there will be a public reaction. Both goalkeepers have played well recently," Klinsmann said.

Klinsmann also said that Hamburg striker Benny Lauth is unlikely to make his squad.

"He's not on our broad list," Klinsmann said.

Lauth was one of Germany's rising stars and played five games for the national team in 2003 and 2004 before his career was interrupted by a series of injuries. After struggling early in the season, Lauth has scored four goals in his last four games.

Germany beat the United States 4-1 last week to blunt some of the criticism directed at Klinsmann and his methods following a 4-1 loss to Italy on March 1.

Klinsmann said a friendly in southern Germany against Luxembourg on May 27 had been proposed, before it kicks off the World Cup against Costa Rica on June 9.

The three-time World Cup champion also plays Japan on May 30 and Colombia on June 2.
