Kalidou Koulibaly was in Chelsea training on Monday after missing's Chelsea draw against West Ham through illness. The Senegal international was absent from the squad that drew with the Irons after suffering an ailment overnight.
The former Napoli star's return comes at an important time with Benoit Badiashile being unavailable for Wednesday's clash against Borussia Dortmund at the Westfalenstadion. The Frenchman has formed a solid partnership with Thiago Silva over the last four games and kept three clean sheets in that peirod but was not among the three players Graham Potter was allowed to add to his Champions League squad for the knockout stages.
Joao Felix, Mykhailo Mudryk and Enzo Fernandez were the trio chosen from January's new signings, while Pierre-Emerick Aubameyang was taken out of the squad to facilitate space for those alterations. The forward has not made either of Chelsea's matchday squads against Fulham and West Ham since that decision was made.
