With the Sydney FC v Urawa Red Diamonds clash just days away, the Japanese team are staying at Sydney's Star City hotel, casino and entertainment complex.

Worried by the possibility of their players being seduced by the bright lights of the 24-hour casino, club officials have taken drastic measures.

Casino secuity at all gaming floor entry points have been issued with the team's mugshots and given strict instructions to refuse entry to any player attempting to hit the tables in the lead up to the match.

The Japanese players must be cursing their lack of foresight in failing to sneak a supply of contraband false nose and moustaches into the country.
