Nagoya Grampus breezed into the final 16 of the Asian Champions League with a 4-1 trouncing of Ulsan Hyundai.

The J-League club remain undefeated in the competition thanks to a brilliant performance at home against Korea's Ulsan who dropped out of second spot on the Group E table.

Yoshizumi Ogawa opened up the scoring in the 14th minute with a diving header which was followed up less than ten minutes later by a powerful header from Yuki Maki.

Ulsan managed to get themselves back in the game prior to half-time through Kim Shin-wook who scored the third header of the contest to make scores 2-1 going into the break.

When play resumed, Ulsan continued to push forward in a bid to grab an equaliser but their efforts went unrewarded and when Nagoya's Davi headed home, in the 59th minute, the contest was almost over.

With scores at 3-1, a poor clearance from Ulsan gave Ogawa a chance to score his second and he took it with a curling shot from the edge of the area.

The loss puts Ulsan in danger of missing the boat to the final 16 after Newcastle Jets overtook them in second place by beating Beijing Guoan.
