Brazilian footballing legend Zico is confident he can send his home nation crashing out of the Confederations Cup.
Japan coach Zico hopes his side can beat Brazil on Wednesday
Zico is now Japan coach and his side faces Brazil in Cologne on Wednesday, knowing a win will take them through at the expense of the South Americans.
"It is an extremely special game for me. When I hear the national anthem I'll be very emotional," said the 52-year-old ex-midfielder.
"But the minute it is over I will be working for Japan."
After Brazil's surprise defeat against Mexico on Sunday, coach Carlos Alberto Parreira is likely to ring the changes as he bids to gain the draw that will take his side through to the semi-finals.
"We'd planned all along to make changes for the third game and that is what we're going to do," insisted Parreira.
Ronaldinho and Kaka could make way, with Juninho Pernambucano - who scored with a superb free-kick in Brazil's 3-0 opening win over Greece - pressing hard for a start.
"Ronaldinho and Kaka have both had tiring seasons in Europe and we may try and ensure that they're fresh for the next game," said Parreira.
He added: "We want to win and go through. This is an important tournament, with all the continental champions, but above all it is a test ahead of the World Cup."
In Wednesday's other match, Mexico - who have already qualified for the semi-finals after two wins - take on Euro 2004 champions Greece, who are already out after two defeats.
Mexico know that a win will lead to them topping the group and coach Ricardo Lavolpe said that he expected his side to improve even further.
"It is satisfying to see how we're growing and able to beat great teams. We're getting better all the time," he said.
Lavolpe's side have gone 19 games unbeaten and if they increase that feat to 20 it would be a new record in Mexican football.
In contrast, Greece have been on a downward spiral since Euro 2004 and have been poor in this tournament - to the bemusement of their German coach Otto Rehhagel.
"I really thought my team would have played better in this tournament," he said.
