Chelsea have adopted a strategy in the past few years where they send their young players out on loan so they can develop elsewhere.
Although very few have gone on to become first team players at the club, it must be said that their policy works.
In the past few years alone, Chelsea have generated £139 million from five players that have impressed on loan - Romelu Lukaku, Nemanja Matic, Kevin de Bruyne, Ryan Bertrand and Nathan Ake.
They've also made a lot more from others who have been sold for lesser fees.
Given Chelsea's success, a number of other Premier League clubs have decided to copy their strategy.
Unsurprisingly, out of all Premier League clubs Chelsea have the most players out on loan this season, with 39 of their players spending this term at another club.
Manchester City are second most with 28 players on loan, closely followed by Wolves with 27.
However, these clubs will have to rethink their loan policy.
That's because, according to the Times, FIFA have sent a warning to Premier League clubs that the amount of players they send out on loan will have to be limited by the 2020/21 season.
FIFA are believed to want to restrict the amount of loanees to 6-8 per season, meaning Chelsea and Man City will have to seriously rethink their strategy.
In even worse news for Chelsea, it is thought that the amount of players being loaned out to one club will also be reduced.
The Blues are involved in a partnership with Vitesse, and regularly send multiple players out on loan to the Dutch club every season.
This campaign, they have three of their youngsters playing for the Dutch club.
They are now set to introduce a rule that means only two players will be loaned to the same club.
This will obviously come as a massive disappointment for Maurizio Sarri and Pep Guardiola.
They will now be largely responsible for developing their own players rather than putting the onus on other clubs.
It is, however, a rule that has needed to be imposed for some time.
Clubs like Chelsea have abused the loan system for some time. Having 39 players out on loan in one campaign is just ridiculous.
Well done to FIFA for identifying the problem and doing something about it.News Now - Sport News
