Press Association Sport academy study - key findings
:: Manchester United academy graduates played a total of 44,055 Premier League minutes in the 2016-17 season, more than double the number of minutes for any other academy.
:: That total featured contributions from 35 players, with West Brom midfielder Darren Fletcher the single biggest contributor with 3,235 minutes. Angel Gomes - who played two minutes in United's victory over Crystal Palace in the last league game of the season - became the first player born in the 21st century to play in the Premier League.
:: Tottenham were second in the list, with Harry Kane contributing 2,536 minutes.
:: Ajax's reputation for producing young talent was underlined by their academy being 10th overall in our study - the highest placing of any academy outside of England.
:: Sheffield United were the biggest English contributor from outside the top flight, with 13,564 minutes. That put them eighth overall.
:: Of the teams finishing in the top six in the Premier League last season, Liverpool's academy made the smallest contribution, with 8,753 minutes overall. That placed them 17th, one place behind Belgian side Genk.
:: Hull's 501 minutes was the lowest total of any top-flight academy, over 1,000 minutes adrift of the next-lowest ranked (Watford on 1,513) and also the only one accounted for solely by their own first-team players, with no Tigers graduate appearing for a different Premier League club.
:: Among clubs outside of Europe, Argentina's River Plate were comfortably the biggest contributors with four players - Manuel Lanzini, Ramiro Funes Mori, Roberto Pereyra and Erik Lamela - racking up 5,883 minutes, led by Lanzini's 2,715 for West Ham.
