GEORGE, South Africa — National team boss Takeshi Okada has admitted Japan will have its hands full against a star-studded Dutch side on Saturday, but is confident the Blue Samurai can build on their winning start to the tournament.

"There are too many players we have to worry about, even on their bench. In attack they have (Robin) van Persie and (Wesley) Sneijder and then, starting or maybe coming off the bench, (Elijero) Elia," Okada told reporters after Thursday's closed training session at Outeniqua Park.

"I could probably go on to name the whole team but let's just say they are a quality side and we need to be extremely cautious."
