MIAMI: Not even half of the spots in the 48-team field have been claimed. The schedule of matches won’t be finalized until December. And other than host nations US, Canada and Mexico, nobody has any idea where or when they’ll be playing. Millions of football fans worldwide evidently don’t seem to mind any of those points. Tickets to next year’s FIFA World Cup officially go on sale Wednesday. The buyers will be those who were selected, out of 4.5 million applicants in a lottery that took place last month, to have the first formal chance to purchase tickets over the next few days.
