Last weekend it was fans throwing stuff onto the pitch, this weekend it's fans setting things on fire. Why the swift and drastic turn for the worse in disgusting fan behavior? Well, derbies, of course.
In Serbia, the Eternal derby was smothered in a haze of fireworks and smoke from both sets of fans. Meanwhile, in Portugal, angry Sporting fans set their section of Benfica's Estadio da Luz on fire because their side lost 1-0. Seriously, they set the section on fire. Here's news footage of how it looked from the outside...
Luckily, firefighters were able to put out the blaze before it could spread beyond that one section. This will probably just be taken as a challenge for Sporting fans the next time around, though.
So remember, kids. Always cover yourself in a flame-retardant gel before attending a football match.
