Natal (Brazil) (AFP) - Japan coach Alberto Zaccheroni implored his team to take their rare chances against Greece or face an early World Cup exit. Both Japan and Greece are fighting for their Group C survival following respective defeats to Ivory Coast and Colombia. But after being outmuscled in a second half which saw Ivory Coast strike twice in the space of two minutes, the Blue Samurai face another bruising encounter in Natal's Estadio das Dunas on Thursday. Thanks to the likes of Giorgos Samaras, Greece are likely to tower over Japan.
