Japan coach Takeshi Okada has told his squad to sober up after beating under-strength Chile and Belgium and brace themselves for a decisive World Cup qualifier against Uzbekistan on Saturday.

“This won’t guarantee us anything against Uzbekistan,” he said after Japan blanked Belgium 4-0 on Sunday following a 4-0 defeat of Chile last week in the three-nation Kirin Cup.

Chile and Belgium, both lacking some key players, drew 1-1 on Friday.
