Japan's under-24 men's team claimed a comprehensive 4-0 win over Jamaica's senior side on Saturday, the final game for the Tokyo Olympic hopefuls before the 18-man squad announcement expected later this month.

Takefusa Kubo's 32nd-minute opener was the pick of the bunch, the 20-year-old cutting in from the right before rifling through the legs of three defenders and the goalkeeper for a memorable goal at Toyota Stadium in central Japan's Aichi Prefecture.

"What we can do is to prepare, there's nothing beyond that," said the playmaker as the staging of the Tokyo Games in the middle of the COVID-19 pandemic remains surrounded by questions. "I think our duty is to get ready in case they do go ahead."
