They're demanding jerk chicken be served in the fan zone.
I don't know what the problem is but my guess would be they're still trying to sort out something about tickets for the fans who have travelled independently. My understanding is they will get some tickets but the Portuguese want the vast majority to go to the fans on the club flights that they can keep bottled up.
But I reckon they'd need 25-30 planes for the club trip, on top of the ones already going. I can't see how Porto airport would be able to handle the incoming flights or stand all of them for the day.
