CB – Kalidou Koulibaly
With Chelsea unable to register Benoit Badiashile for the Champions League, it means the Frenchman won’t be available for the trip to Germany.
Potter will have to make a decision between Koulibaly and Trevoh Chalobah as to who partners Silva in the centre of defence.
Despite struggling since his arrival from Napoli last summer, the 31-year-old is likely to be given the nod.
