FIFA have issued a statement after England fans were caught up in ticket chaos prior to their World Cup opener against Iran.
FIFA's app used for tickets appeared to crash in the build-up to Monday's games. Supporters said that their tickets had disappeared off the mobile app, while any user who has logged out in the past 24 hours found themselves unable to log back in.
A number of fans posted screenshots of the defective app on social media, and footage on social media showed irate fans stuck in huge queues outside the stadium. Some with VIP tickets were also believed to be caught up in the chaos, with reports of some fans queuing for two hours but failing to gain entry to the stadium for kick-off.
