Chelsea midfielder Romeo Lavia is back available for selection after recovering from a thigh muscle injury.
The Belgian international was present with the rest of his teammates during an open training session ahead of the game against Legia Warsaw.
Lavia has not played since coming on for the final 10 minutes of the 1-0 defeat to Arsenal at the Emirates just over a month ago.
The 21-year-old is NOT in the Conference League squad so his return to action will have to wait until the weekend.
