For this year’s rankings I followed the same methodology used by Mark Crane for his previous editions.
A list was compiled of male English players (ie players eligible in the 2020/21 season to play for the England men’s national team) who played in at least one match for any team in the top five English leagues, based on data from the www.fbref.com website.
Information on the Academy, or Academies, attended by each English player who had made at least one league appearance was then collated and cross-referenced from information in Wikipedia, club biographies, news sources and www.transfermarkt.co.uk
An Academy, Centre of Excellence, or other club training structure was counted as having contributed to a player’s development if he was in attendance there at any point up to the age of 18.
There are players who may have been produced by these Academies who for various reasons may not be included in the research. Players who are not listed as English on www.fbref.com were not included. So players like Wilfried Zaha, who was developed by Crystal Palace but is listed as from the Ivory Coast, were excluded.
Furthermore, Welsh teams like Swansea and Cardiff City suffered tremendously in these rankings as most of their graduates are Welsh and not English. Players who were signed or on loan in other countries did not count towards the rankings either.
