Zico fuming at European clubs
The former Brazilian great is currently waiting on best player Hidetoshi Nakata of Bologna, while fellow Italian-based player Shansuke Nakamura of Reggina is also not yet with the squad.
Neither are Fulham's Junichi Inamoto or Shinji Ono of Dutch giants Feyenoord - much to the anger of Zico.
"We are very near to the day in which we have to play against Singapore and I still don't have the players that I need," said Zico.
"Some of them are the most important players of the team and I still don't have them for training. This isn't the way I had planned that I was going to work for the Japanese national team."
