I found this article interesting - selective quotes
"Thirty players at the 2022 men's World Cup in Qatar were born in the vicinity of France's capital. Compare that to two other hotbeds of youth football: Sao Paulo provided 12 World Cup players and Greater London eight.
There were 11 Parisians in the France squad that lost to Argentina in the final, with the other 19 spread across eight national teams: Morocco, Tunisia, Senegal, Ghana, Cameroon, Portugal, Germany and Qatar.
And then you have the icons of the recent past. World Cup winners Thierry Henry, N'Golo Kante and Paul Pogba all grew up in the banlieues(suburbs) of the French capital, as did Kante's former Leicester team-mate Riyad Mahrez.
How has Paris become a city that churns out more football talent than anywhere else?"
"A local government policy of building high-quality football facilities in every Paris banlieue, partly to keep kids off the streets and out of trouble, has been fundamental to making the sport cheap and accessible to all."
"The Ligue de Paris Ile-de-France has more than 1,000 clubs and 270,000 players. It's such an important organisation that it has an office in the picture-perfect Place Valois, a well-struck free-kick away from the Louvre museum, right in the heart of Paris."
How people, policy and the shortcomings of the city's premier club have helped Paris export players in a quantity and quality unmatched anywhere in the world.
