England midfielder Frank Lampard believes a combination of high altitude and the new Jabulani World Cup ball will cause chaos in South Africa.

A series of goalkeepers have condemned the lightweight ball introduced specially for the competition, which seem to deviate in the air and England used one for the first time against Japan in Graz, when Lampard was almost one of the early beneficiaries with a 40-yard effort that dipped viciously.

"The altitude won't be a problem," said the Chelsea star. "But the ball moving around will be an issue because it moves a lot more. The goalkeepers will tell you that."
