Four of the eight teams that have qualified to the quarter-finals of the Rugby World Cup are coached by New Zealanders.
This includes Steve Hansen who is the Head Coach of the All Blacks, Joe Schmidt for Ireland, Jamie Joseph for Japan and Warren Gatland for Wales.
Hansen and Schmidt will go head-to-head this Saturday, so it will be the end of the tournament for one them.
Hansen, Schmidt, Joseph and Gatland share similar backgrounds; all showed ability as players but Joseph and Gatland were All Blacks, while Hansen and Schmidt played at provincial level.
Schmidt says the All Blacks have been the benchmark for a decade and beating them at the Rugby World Cup would be a mountain to climb.
Looking at the quarter-finals this week, Australia will face England at 7.15pm this Saturday, All Blacks will play Ireland at 10.15pm, Wales will take on France at 7.15pm this Sunday while Japan will face South Africa at 10.15pm this Sunday.
