The ugly face of football: Inside rising hooliganism in the stands as new C4 documentary follows officers trying to clamp down on violence, disorder and anti-social behaviour blighting the beautiful game

The ugly face of football has been laid bare in a new documentary that follows officers as they try and managed feuds between bitterly divided teams.

Football Cops on Channel 4 takes an inside look at the country's Dedicated Football Officer's (DFO) who work to tackle the violence, disorder and anti-social behaviour at games.

Kicking off the series the DFO had to manage a bitter feud between Coventry City and Sunderland, whose entrenched hatred of each other goes back almost 50 years to a decisive game that saw Sunderland relegated and Coventry fined for 'influencing an outcome'.
