Belgrade - Serbian goalkeeper Vladimir Stojkovic joined the avalanche of criticism directed at the World Cup ball, saying it was heavily favouring strikers, the Vecernje Novosti daily reported Wednesday.
"It's a catastrophe. I played with many different balls, some of which wiggled or changed direction, but this one is the worst of them all," he said in an interview. "It is definitely favouring strikers, to increase the number of goals at the Mundial."
The flight of the ball - named Jabulani, which means "to celebrate" in the isiZulu language - is "unpredictable" and tends to "dip quickly" Stojkovic said.
"As it has been going, I expect the attackers to get a set of pistols for the next World Cup," joked Stojkovic, currently on loan from Sporting Lisbon to English side Wigan.
The Serbian squad went to the Austrian Alps for altitude training ahead of the World Cup. It lost a friendly against New Zealand 1-0 in Klagenfurt and was set to play Poland on Wednesday, again in Austria.
Serbia, which is in World Cup Group D with Ghana, Germany and Australia, has its final friendly test against Cameroon in Belgrade on June 5 before setting off for South Africa.
