All the established teams, such as Engerland and Argentina who have been in the WC regularly have lots of skillz.
But all the new African teams are a LOT more energetic, their players are a lot more speed and power just because they are gifted because they are black.
So right now, although the skillz teams are doing better, the gap between these skillz teams and the new teams has been shortening greatly. This is seen by Brazil vs Croatia, who dispite having 6 superstars almost lost to Croatia. (yes I know Croatia is in Europe).
So the new African teams will eventually perfect their skillz and have superstars as well. Give it a couple more years and black people will dominant the WC just like in the NBA.
Dammit they're just much better athletes .
