Mateo Kovacic and Kepa Arrizabalaga were both absent from Chelsea's open training session ahead of their final UEFA Champions League group match against Dinamo Zagreb on Wednesday evening.
Graham Potter and his squad were training at Cobham in an open session on Tuesday morning but they were without Kepa and Kovacic. Kepa limped off at half-time in Saturday afternoon's 4-1 defeat at Brighton & Hove Albion.
Meanwhile, Kovacic has been struggling with a calf problem in recent weeks but he did complete 90 minutes at the Amex Stadium at the weekend. The Croatian wasn't present at Cobham on Tuesday morning, though.
