They say not everything can go off without a hitch and there was a second ticketing fiasco at the FIFA Women's World Cup.
FIFA and French officials came under fire last month for allocating seats issues which saw fans not seating with each other despite buying tickets together.
After the fiasco in May, FIFA said they were working with the local organising committee to resolve the issue.
In the process, some fans reported tickets that had been delivered electronically were no longer available, with the message: "FIFA and the LOC are currently working on improving the seating arrangements for certain orders for a limited number of matches. If your order is affected, please expect to receive a dedicated communication shortly."
However, in trying to rectify that issue for the opening sellout game between France and Korea Republic on Friday night, there were still issues.
Some fans found themselves having to queue up to have their tickets re-issued after seating allocations were changed before re-lining up again to get into Parc des Princes.
Those who had e-tickets printed at home had not been warned about the change in seating allocation.
Chaos unfolding at the Parc des Princes in Paris. Thousands of supporters are likely to miss kick off. Stewards can't cope and ticket fiasco causing difficulties at the gates. #FIFAWWC #FRAKOR pic.twitter.com/1roAZjUsAy— Claire Bloomfield (@DifferentClaz) June 7, 2019
One Australian fan reported having to wait an hour to get into the stadium.
