The two clubs are the only English academies to be able to boast of more than one player currently among the game's 112 highest earners, according to a new study from Norwegian financial consultants Axo Finans.
Southampton produced Theo Walcott and Gareth Bale, now at Arsenal and Real Madrid respectively, while Leeds United graduates Fabian Delph and James Milner enjoy bumper pay cheques at Manchester City and Liverpool.
While 43 per cent of all players with a stated salary over €100,000 per week now play in the Premier League, English academies themselves trained just 15 of those players — 13 per cent.
Barcelona and Brazil best for big bucks
Axo Finans' study found that Barcelona's famed La Masia academy deserves its reputation as a factory of footballing superstars with six graduates (Lionel Messi, Andres Iniesta, Cesc Fabregas, Sergio Busquets, Gerard Pique and Pedro) currently among football's highest earners, more than double any other club in the world.
The next best academies for high earners are Brazil's FC Sao Paulo, Bayern Munich and Valencia with three players apiece.
Brazilian academies have produced 19 of the world's best-paid players, more than any other nation, but none still play in their home country.
After the Premier League, Spain's La Liga and the Chinese Super League account for the most players earning over €100,000 per week with 17 each — 15 per cent.
All of those have arrived in China in just the last two years, with 13 having arrived in 2016 alone.
