Torres Heroics
Torres needed just six minutes to break New Zealand’s resistance.
He controlled a David Villa pass on the edge of the area and curled a delightful right-foot shot into the top corner.
On 14 minutes, Albert Riera released Villa with a deft through pass on the left flank.
The Valencia striker sent in a low cross for Torres to easily convert the ball past New Zealand’s hapless keeper Glen Moss.
Three minutes later, Torres completed his hat-trick when he rose unmarked to head home Joan Capdevila’s pinpoint cross.
Fabregas heaped more misery on New Zealand in the 24th minute with an easy tap-in after the lively Capdevila cut the ball back for him.
New Zealand pushed forward afterwards in search of a consolation goal but were not able to create any clear-cut opportunities.
Villa completed the rout three minutes after the restart after capitalizing on a dreadful blunder by Andrew Boyens.
The New Zealand defender tried to clear Torres’ cross but his mis-hit kick allowed Villa to fire a low shot home from close range.
