Arsenal boss Arsene Wenger has said that television cameras have helped to clean up football.
The Frenchman, who insists that the sport was much dirtier in the past, has said that putting games under the microscope of television cameras has forced football to "clean up its act".
"The cameras have done a lot of good work for the game," he told the club's official website.
"Football has cleaned up its act because it was dirtier 25 years ago. It is much cleaner today because everything in Europe is checked. I remember having played some games in Europe 25 years ago and away from home it was not all clean because it was not filmed.
"Today even in the hardest derbies you have people greeting each other before a game - you couldn't see that 25 years ago. The tank of hate was much bigger."
The Gunners are currently in seventh place in the Premier League with 19 points.
