Thiago Silva and N’Golo Kante will be injury doubts for Chelsea’s Premier League clash with Brighton on Wednesday.
Defender Silva hobbled out of the 3-1 Boxing Day win at Aston Villa with a thigh issue, though Chelsea hope to have caught the problem before a major flare-up.
Kante will be checked for a knee issue, while Timo Werner and Kai Havertz could return after Covid isolation but Ruben Loftus-Cheek is a doubt with a foot injury.
Brighton will assess forward Leandro Trossard after hamstring tightness forced him out of the Boxing Day win over Brentford.
Midfielder Yves Bissouma returns to contention following a one-match ban, while defenders Joel Veltman and Shane Duffy could return after missing out against the Bees.
Midfielder Steven Alzate and forward Danny Welbeck returned from three-month injury absences as substitutes against Thomas Frank’s side but captain Lewis Dunk (knee) remains out.
