The new Adidas Jabulani ball has been criticised by the likes of David James, Iker Casillas and Gianluigi Buffon, and Stojkovic is equally concerned.

He told "I have played with many different balls in my time - those that swerve a lot, change direction, fly awkwardly - but this one is definitely the worst of all.

"It has been intentionally made to suit outfield players and to contribute to a high number of goals at the World Cup."
