London has the traditional model of centralizing a big stadium, it was popular in the prewar era.
After war, mostly because of the Blitz and Hiroshima on respective sides, the ultimate plan of both Western and Eastern cities was sprawl.
Paris' football culture really didn't start until the 70s, and therefore the stadiums their clubs built were all on the fringes of the city.
After the SALT treaties and the layered-on Arab Oil Embargo you started seeing people leaning into cities gradually and today Millennials and Zoomers are typically on the side of "why did people ever move to the suburbs?"
But ultimately it's because the Nazis leveled Central London over a couple years and the Americans discovered a bomb that could destroy a central business district with one click.
Once those bombs were made relatively obsolete, the concept of war became further away for most urbanites and especially after the plummet in crime rates in the 90s-00s people look at an approach like this and go "why"
But if you look at stadiums of that era, the only major stadium built anywhere near the center of a city was Madison Square Garden and that only came to fruition over an infamous bureaucrat's infamous megalomania and included putting America's largest train station underground where it remained until a couple years ago.
