Tickets for the 2014 FIFA World Cup in Brazil have gone on sale - despite worries that some of the stadiums are still under construction.

FIFA, the world governing body for football, expects demand for tickets to match that of the 2006 World Cup held in Germany, when more than 3.3 million tickets were sold.

According to FIFA, there were about seven applicants for every ticket of the 64-match tournament in 2006.

Ticket prices for the 2014 World Cup tickets range from around £58 (US$91, 68 euro) for group stage matches to £633 (US$991, 742 euro) for the most expensive final tickets at the Maracana Stadium in Rio de Janeiro.

While the 2014 World Cup is expected to be a ticketing success, there has been concern over the fact that some of the stadiums hosting matches are still being built.

Last week, the country's sports minister Aldo Rebelo admitted he was "worried" about delays to the construction of some of the new stadiums.

Rebelo warned that five of the venues - in Manaus, Curitiba, Cuiaba, Porto Alegre and Natal - will not be delivered on time unless construction work is accelerated on the venues.

• Tickets have also gone on sale for the 2014 Commonwealth Games in Glasgow. Around one million tickets went on sale on Monday morning, with high demand putting pressure on the online ticket system and causing long delays reminiscent of those experienced when tickets for London 2012 went on sale.
