WATCH: Tough night in Asia for A-League clubs

Managed by former Australia, Brisbane Roar and Melbourne Victory coach Ange Postecoglou, Yokohama raced to a 3-0 lead inside the first 35 minutes thanks to a goal from Ado Onaiwu and a double from Teruhito Nakagawa.

Postecoglou's J.League champion dominated possession 60 percent to 40 percent against a Sky Blues outfit missing influential creative midfielder Milos Ninkovic, who wasn't included in the club's champions league squad under the conditions of his new deal.

Onaiwu added a fourth goal midway through the second half as Yokohama maintained its unbeaten start to the tournament.
