Japanese World Cup star Keisuke Honda has stated 'nothing is impossible' after his nation reached the last 16.
Honda struck a wonderful free-kick on Thursday to help the Japanese secure a 3-1 triumph over Denmark.
Japan next face Paraguay and Honda has warned their South American opponents that confidence is high amongst his team-mates.
"For Japan it's a big win," Honda said. "I'm glad we won but I am not satisfied.
"The next game is more important. I want to show the Japanese that nothing is impossible."
Honda also reserved praise for head coach Takeshi Okada, who urged his team to attack Denmark despite them only needing a draw.
He continued: "Prior to the match, the coach said we shouldn't concentrate on the defence and that we should attack.
"That's what the coach told the players to boost our motivation. It was really effective and led to this wonderful result."
