Academy Productivity Rankings 2017/18: Manchester United retain top spot

Manchester United have again come out on top in our annual Academy Productivity Rankings – the only publicly available resource of its kind.

The research has been produced by Mark Crane and is this year presented in association with Mammoth Mattresses. The data is based on the Academies (Category 3 and above) attended by England-eligible players who made at least one league appearance in the 2017/18 season.

This year a weighting has been applied based on the level at which the players featured last season. You can see a full methodology below the table. The figures outside the brackets are total number of players, while those inside represent players aged 16 to 18.
