The law could force the club to drastically change the way they manage their squad.
According to Bild, FIFA is planning to restrict the number of players sent out on loan to only eight per season.
The Blues currently have about 40 players on loan to other clubs.
The limit would mostly apply to players over the age of 21, with homegrown youngsters exempt.
Of Chelsea’s 40 loanees, only 16 would currently count as homegrown youngsters.
The club would now need to trim their number of other loanees down from 24 to eight.
Omeruo has spent all the season’s as Chelsea on loan to other clubs and is currently on a season-long loan to Leganes in Spain.
