Research, available in full here, focuses on the Academies attended by all England-eligible players who made at least one league appearance in the 2020/21 season.
With 69 Academy graduates featuring across English football last season, United and Arsenal lead the way in the rankings. By way of having more graduates at a higher level (in the highest two divisions), United are clear of our Premier League rivals at the summit.
This year's rankings are the third set produced by Training Ground Guru. In previous editions, in 2016/17 and 2017/18, United were also top.
