Japanese top flight club Omiya Ardija were stunned by university students after being beaten on penalties in the second round of the Emperor's Cup on Monday.
Fukuoka University produced one of the biggest upsets in recent times in a 5-3 shootout victory following a 1-1 draw after extra-time.
"We're pathetic," Omiya midfielder Daigo Watanabe told Japanese media. "We just let them ping long balls at us and it was an accident waiting to happen."
Fukuoka coach Masahiro Inui enthused: "The players were fantastic. They kept cool in the penalty shootout and really did us proud."
