Chelsea duo Reece James and Christian Pulisic are sweating over their fitness ahead of the resumption of Premier League action.
The Blues take on Brentford on Saturday in the league, and they could be without two key players.
According to The Independent, Pulisic has been injured since the previous international break, and has still not returned for training.
James suffered a problem against Manchester City recently, before getting an England call-up.
However, he withdrew from the squad, as he was not fit to play.
