Danish neighbours FC Copenhagen and Brondby are hardly the best of friends. In fact, they're fierce rivals and have been for a very long time. This tifo by FC Copenhagen's fans from a Superliga derby game in 2014 shows just how much hatred there is between the two Danish giants.
The tifo showed Copenhagen obliterating Brondby's home ground with a cannon; two rounds of artillery blowing the Brondby Stadion to smithereens, before a giant banner was unfurled to reveal that "Copenhagen is ours!".
The game itself ended in a slightly dull 1-1 draw, with this tifo providing most of the entertainment.
Nothing like a bit of creative hatred, eh?
