Jens Lehmann
Maier went into coaching for both club and country and mentored Oliver Kahn. In October 2004 his contract with the national side was terminated by manager Jürgen Klinsmann after Maier spoke out in favour of Kahn over Arsenal's Jens Lehmann in a dispute over who should be the side's first-choice goalkeeper. He continued to work as head goalkeeping coach for Bayern and retired in 2008.
