Bayer Leverkusen goalkeeper Rene Adler is expected to be Germany's starter at the World Cup.

Germany goalkeepers' coach Andreas Koepke said Monday that Adler will be in goal for this week's friendly against Argentina. Wednesday's match is Germany's last before the squad for South Africa is named in May.

The 25-year-old Adler is in a three-way battle for the starting spot with Werder Bremen's Tim Wiese and Schalke's Manuel Neuer.

Koepke said Adler is "No. 1 at the moment" and that the position is his to lose.
