Arsene Wenger says society must deal with all forms of discrimination in an "extremely severe" way.
The Arsenal manager's comments follow an incident involving Chelsea fans at a Paris subway station on Tuesday.
Wenger was dismayed at the actions of those involved and believes education has a vital role to play in eradicating racism.
"It certainly starts from childhood education and an open-minded attitude"
“More intelligent people than myself think about that and nobody has found a miraculous solution,” the boss said. “It certainly starts from childhood education and an open-minded attitude.
“It looked pathetic and dreadful. Unfortunately we always have a recurrence of that. You have to be extremely severe with any incident of that calibre.
“There is a danger of having radical people in every society. Since I observed youth movements, there are always certain people who are ready for radical solutions and most of the time you have to control them.”
