If national team manager Takeshi Okada has learned one thing from his side's recent Kirin Cup matches, it must be to trust his own instincts.
Okada took over from previous incumbent Ivica Osim when the Bosnian suffered a stroke late last year, giving the new man little time to stamp his own imprint on the side before World Cup qualifying began in February.
Okada pledged to change little from the Osim era for the sake of continuity, but a 1-0 defeat against Bahrain in March prompted a dramatic rethink.
