England play their first match in New Zealand for a decade as they look to shock the All Blacks in Dunedin on Saturday morning.

Here, the PA news agency examines five talking points heading into the first of two Tests between the rivals.

The ultimate challenge

England wins against New Zealand on Kiwi soil are precious and have been managed only twice before – in 1973 and 2003. Since Martin Johnson’s team prevailed against the odds over two decades ago, England have played seven more times in the All Blacks’ back yard and got close only once, a 20-15 defeat in Auckland in 2014. South Africa are world champions, but outside the global showpiece winning a Test series in New Zealand is the sport’s ultimate challenge.

Chinks in armour

The All Blacks are heavy favourites to triumph at Forsyth Barr Stadium, yet they have rarely appeared so vulnerable. Their first outing of the year takes place under a new head coach and captain in Scott Robertson and Scott Barrett respectively, while influential stalwarts such as Richie Mo’unga, Brodie Retallick and Aaron Smith have either retired or are on sabbaticals in Japan. Factor in player unrest with administrators and the Crusaders fading as the dominant force in Super Rugby and it seems to be a good time to be facing the World Cup runners-up.

Smith’s moment of truth

If ever there was a moment for Marcus Smith to prove he is England’s principal fly-half it comes in Dunedin. Smith was electric in the tour opener in Tokyo a fortnight earlier, but the space provided by Japan’s defence was a gift to a player with his attacking repertoire. New Zealand will be far less accommodating, but if Smith’s decision-making and game management match his creativity with the ball in hand, the jersey will be his for the foreseeable future.

Savea v Earl

A thunderous collision awaits at number eight where Ben Earl and Ardie Savea go head to head. New Zealand’s Savea is the current world player of the year, a dynamic back row who is at his best in attack but also a force at the breakdown. Earl has displayed similar strengths since taking last autumn’s World Cup by storm and while they are not the biggest operators in their position, they have the explosive power to blast through tackles.
