Arsenal have continued their pre-season tour of Asia with a 3-1 win over Arsene Wenger's former club Nagoya Grampus in Japan.

It took the Gunners three minutes to open the scoring as Olivier Giroud headed in Tomas Rosicky's cross to net his eighth goal in three games.

They doubled their advantage midway through the first half when Ryo Miyaichi converted from the penalty spot following a handball from Marcus Tulio Tanaka.

Theo Walcott added a third on the hour mark with a neat finish after being picked out by youngster Gedion Zelalem's incisive pass.

The hosts pulled a goal back through Kisho Yano's header on 72 minutes, but they were unable to further breach the Arsenal defence.
