It’s semi-finals time at the 2019 Rugby Union World Cup in Japan this weekend and there’s two heavyweight clashes between New Zealand and England tomorrow and South Africa and Wales on Sunday. New Zealand and South Africa are clear favourites to win their respective matches, but I don’t see it being plain sailing for the Southern Hemisphere giants because England and Wales have closed the gap on their rivals this decade. If there’s going to be an upset, Wales look most likely to cause one given their good record against the Springboks in recent encounters.
