England football fans hoping to travel to the World Cup finals in South Africa have been warned about ticket scams.
And Foreign Office (FO) travel advice warns of the dangers of crime in South Africa, particularly in parts of Johannesburg.
Travel organisation Abta said some fans might book trips where promised tickets to the matches failed to materialise.
Following England qualifying for next summer's finals after Wednesday night's 5-1 win at Wembley over Croatia, UK tour operators were quick to publicise special World Cup packages.
Trips with Thomas Cook Sport, for example, will start at £2,499, with flights departing from London and Manchester.
The company is one of the official 2010 World Cup tour operators and Abta said it was vital fans booked with this type of company.
Earlier, Prime Minister Gordon Brown paid tribute to England's football team for "emphatically" beating Croatia to win a place at next year's World Cup finals.
Mr Brown kept an eye on both the England-Croatia and Scotland-Netherlands qualifying matches - but while Scotland slumped to a 1-0 defeat, England took an emphatic victory.
The Prime Minister said: "Many congratulations to Fabio Capello and the England team for qualifying for the 2010 World Cup Finals with tonight's emphatic win against Croatia.
"The country looks forward to supporting the team in South Africa next summer."
