There's always been controversy about how many top-tier English clubs have so many non-British players on their books (no-one seems to mind if the team includes Welsh or Scottish players...), and in a few cases there have been teams put out that didn't even have one Brit in the starting lineup. The English Premier League is incredibly wealthy, so buying foreign players is routine, and the selling clubs, often clubs in straitened circumstances, are often glad of the transfer fees. A possible upshot of that is that we don't produce enough home-grown players to generate an effective national team. Some clubs, to their credit, have strong academies these days to develop the skills of up-and-coming Brit kids. But none of this is ever about black players, and this is after all a thread about national teams, apropos of which the rules about who can be included are much stricter.
