The Croats put a swastika on the feel ffs and got away with a 1 point deduction. Just enough so they can still qualify and all is forgotten. You may say yes but it was one fan, but there have been loads of other times Croats have been involved in rioting. They are one of worst countries for violence at tournaments. Possibly the worst.
We have a pathetic pitch invasion against Andorra, where the stewards didn't control the situation and we almost get deductions.
The most laughable was Man United Mariselle. UEFA proved my point.
UEFA LAUNCH PROBE INTO FLARE USE AT MARSEILLES MAN UNITED.
