Newcastle United have begun their pre-season tour of New Zealand with a 4-0 victory against Sydney FC in Dunedin.

New signing Siem de Jong got the Magpies on their way in the 18th minute, capitalising on a mistake from Ivan Necevski before firing the ball home.

Alan Pardew's side doubled their lead six minutes later, when Yoan Gouffran squared the ball for Emmanuel Riviere to score from close range on his debut.

Sydney struggled to cope with their Premier League opponents and fell even further behind on 31 minutes, when Mapou Yanga-Mbiwa's effort from distance took a big deflection before finding the bottom corner of the net.

Ayoze Perez almost added a fourth midway through the second half, but he blasted his shot over the bar from a tight angle. However, Andy Armstrong made the score 4-0 with 10 minutes remaining.

The 17-year-old collected Paul Dummett's pass before firing a composed finish beyond Necevski to round off a convincing victory for Pardew's men.
