BONN -- Japan 'keeper Yoshikatsu Kawaguchi said he was "sickened" by the manner of the Boys in Blues' 3-1 defeat at the hands of Australia on Monday in Kaiserslautern.

Kawaguchi looked a dead certain for man-of-the-match after pulling off a string of brilliant saves as Japan protected its 1-0 lead courtesy of a hotly contested 26th minute goal by Shunsuke Nakamura.

But a moment of madness by Kawaguchi let in substitute Tim Cahill for Australia's equalizer on 84 minutes, and the Aussies scored twice more for a stunning victory in the Group F opener.
