Sorry, when I said it had to be something pretty major for it to be reported in England, I was referring to what goes on in Spain, in reply to AFU's question of whether it was maybe just better reported than in years gone by.
There was also quite a bit of trouble outside the ground before the Atletico v Real Madrid derby on Saturday, quite a few car windscreens smashed. Gets a brief mention in here
