Why did the ethnic balance of the French national football team change between 1986 and 2018? [closed]
Today I noticed that the ethnic balance of the French national football team has changed significantly over the last 30 years. In the 1986 World Cup, the vast majority of the players were white, however, in the 2018 World Cup-winning squad there were significantly more black players.
What major change took place in France between this time so that the number of black soccer players increased dramatically in the French national team?
If it is because of immigration, why did the immigration increase suddenly?
