Jens Daniel Nowotny is a German former professional footballer who played as a defender.
He played in nearly 300 official games with Bayer Leverkusen in one full decade, helping them reach the 2002 Champions League final. In his prime, he is widely regarded as the best defender in Germany.
Internationally, Nowotny appeared for Germany in one World Cup and two European Championships, gaining 48 caps.
Nowotny was then picked for the 2006 World Cup in his country, after two years of absence from international football. However, the experienced stopper spent the whole tournament as backup to younger Christoph Metzelder and Per Mertesacker, only playing in the third-place play-off against Portugal (3–1 win), as stand-in for the injured Mertesacker. In total he won 48 caps, scoring his only goal in a friendly match, a 7–0 victory over Malta on 27 May 2004.
