Romeo Mitrović, of the Bosnian second division side Bratstvo Gračanica, does not like refs. He doesn't like their cards, he doesn't like their attitude, and he especially doesn't like their faces. Which is apparently why he tried to split one ref's wig after being shown a yellow.
Next time, the refs will know not to step to Big Romeo with that yellow card nonsense. Assuming he ever gets to play again, that is.
