The top 10 most valuable academies in the world have been revealed, showing which clubs are making the most money out of their young players.
There's very little in football that fans love more than seeing someone come through the club's academy to make a big difference to the first team.
Most clubs have had some sort of variation of the 'he's one of own' chant, that is heavily associated with Harry Kane these days, at some point or another.
Manchester United take their academy so seriously that at least one player who has graduated from it have been in every matchday squad for the past 85 years.
The club's most prominent academy graduates came from the famed 'Class of 92' but even on Sunday, in the win over Brighton in the FA Cup semi-final, Marcus Rashford played a very important role, and several others are currently in Erik ten Hag's squad.
However, the Premier League side aren't good at selling their players for that much money, and it appears the same can be said when they come through the academy.
According to the stats, they aren't in the top 10 most valuable academies, when it comes to the most money earned from players, whilst three of their rivals from England's top tier are.
As per CIES Observatory, Chelsea, Manchester City and Arsenal are all better at selling their young stars, although they all fail in comparison to one of Europe's top exporters.
10. Arsenal - €400 million
9. Flamengo - €438 million
8. Santos - €445 million
7. Sao Paulo - €475 million
6. Paris Saint-Germain - €490 million
5. Manchester City - €510 million
4. Ajax - €555 million
3. Barcelona - €580 million
2.. Chelsea - €630 million
1. Benfica - €670 million
Benfica certainly have a happy knack of selling their players for good money, whether they're academy graduates or players they've bought for a lot less than they sell for.
Joao Felix was sold for €127 million, whilst Enzo Fernandez went for a British record fee last January, just six months after the club signed him for around €10 million.
