New Zealand head coach Ian Foster said on Saturday he remained confident of his side's chances at the Rugby World Cup despite the 27-13 loss to hosts France in the opening match.For the three-time winners of the World Cup, the defeat was their first ever in the pool phase of the tournament."I don't think we have to rebuild," Foster told reporters."In the past we've won all our pool games and not won the tournament. "Our goal is to win this tournament," he added, with New Zealand having won the inaugural World Cup in 1987, before claiming back-to-back titles in 2011 and 2015.Minutes before the game, captain Sam Cane was ruled out with a back issue which he suffered in training on Thursday."He felt his back get strained so he was pretty stiff last night," the 58-year-old Foster said."We had a look at him late morning and made a decision to pull. "He was moving well tonight but because we didn't have real clear information on how bad the back was, we pulled him," he added.A big turning point at the Stade de France was a second-half yellow card for winger Will Jordan for taking out Les Bleus fullback Thomas Ramos in the air.Minutes after returning from the sin bin Jordan was penalised for a similar incident, but avoided a red card.Ramos then kicked the resulting three points to give his side a 19-13 lead with a quarter of an hour to play."Will was a bit clumsy with aerial things and the second hurt us," Foster said."We have to get more efficient in the air."READ | France victory the desired result for World Cup, New Zealand left staring at low road to historyAnother negative element of the All Blacks' performance was at set-piece with France's New Zealand-born tighthead prop Uini Atonio getting the upper hand over Ethan de
