Peru failed to break down a resolute New Zealand defence in a 0-0 draw in Wellington on Saturday, leaving their dream of ending a 36-year absence from the World Cup finals hanging by a thread.
Although Peru tried to score away goals, the captain and the defender of New Zealand national team Winston Reid showed his skills to make obstruction.

"We're used to playing away from home".
The All Whites were under pressure nearly immediately, a disastrous start averted as keeper Stefan Marinovic back-pedalled to claw away a near own-goal after a miscommunication between skipper Winston Reid and Tommy Smith at the back.

After being outplayed early, it was New Zealand who had the better of possession in the second half, although Peru's Aldo Corzo forced Marinovic into a sharp save with a powerful header.
The visitors dominated in midfield, allowing Andre Carrillo to pepper New Zealand's box with crosses searching in vain for a finish from striker Jefferson Farfan.
Star New Zealand striker Chris Wood, who surprisingly started on the bench, came on with less than 20 minutes remaining as the home side pushed for a victor.
Wood is expected to start in the return leg on November 15 at the Estadio Nacional in Lima, while Peru are likely to still be missing Guerrero.
Peru has qualified for the World Cup on four previous occasions, reaching the quarter-finals in 1970, but has not made it back since 1982.
