Chelsea are low on numbers, especially in defense and midfield, and the international break might have added more names to the injury list.
Enzo Maresca is without his star player, Cole Palmer, until November, and Moises Caicedo, Andrey Santos, and Dario Essugo are all missing from the midfield.
Two more players have been sent home from the international break, and both could miss the Premier League return against Nottingham Forest.
Which Chelsea players have returned to Stamford Bridge from international duty?
Argentina star Enzo Fernandez has withdrawn from international duty after suffering from knee inflammation.
Fernandez has been crucial for Chelsea, playing more league minutes than any other Chelsea player, besides Caicedo.

The midfielder will miss Argentina's friendly against Puerto Rico, although he was slated to be rested for that match.
There has been no official statement on how long Fernandez will be sidelined for, but Chelsea's next match comes on October 18, with a quick turnaround time for the star to play.
Another concern is the health of youngster Estevao, who is dealing with the flu.
The Brazilian might miss his nation's match against Japan, with the national team monitoring his status.
While he could be healthy in the coming days, the long flight from Japan back to London could take a toll on the 18-year-old.
Maresca will have to assess Estevao's status, especially with Chelsea slated to play seven matches in less than a month.
