Olsen made his comments following a 1-0 defeat by fellow finalists Australia in a warm-up match in Johannesburg.

He said: "We are playing with an impossible ball but we will just have to get used to it.

"That's not an excuse, it is a cause. We had trouble controlling the ball and getting any pace on our passes."

Arsenal striker Nicklas Bendtner sat out the game with a thigh injury while defender Simon Kjaer is struggling with a knee problem.
