World Cup: Close-up look at football for tournament

With the 2010 World Cup just one month away, teams will soon be heading to South Africa for the last stages of their training.

Jonah Fisher visited Stellenbosch University where Warren Engelbrecht talked him through the effects of altitude on the performance of the ball.
