Thursday night in Serbia saw Red Star Belgrade, otherwise known as Crvena Zvezda, pick up a 1-0 win away at Novi Pazar.
Away from the action on the pitch there was plenty to watch in the stands as the visiting fans caused trouble for local police and themselves.
During the match armed riot police confronted the Red Star supporters when they set fire to a banner.
Separately, one Red Star fan was taken to hospital with serious injuries after he stupidly climbed up a three meter high metal fence before losing his balance and dangerously falling on the hard concrete below.
