FIFA has reportedly warned Chelsea and other Premier League clubs that they have just one more season to complete an overhaul of their squads to comply with new loan laws.
The regulations, due to be rolled out from the start of the 2020-21 campaign, restricts the number of players teams send out on loan per season.
According to The Times, FIFA has contacted the Blues to remind them of the rule change, which it is claimed will have huge implications for the club's business model.
Teams will also be capped on the number of players sent on loan to a single club, which would again adversely affect the Londoners as three of their youngsters are currently with Vitesse in the Eredivisie.
In all, Chelsea have 39 players out on loan from their first team, Under-23s and academy, while Manchester City (28), Wolverhampton Wanderers (27), Brighton & Hove Albion (16), Watford (14) and Everton (14) are next on the list.
