Graham Potter has been dealt another blow to his squad options this week with news that Raheem Sterling could miss today's trip to West Ham. The forward returned to action in last week's draw with Fulham after picking up a hamstring injury in the defeat to Manchester City.
However, the Chelsea boss confirmed on Friday that the England international would be assessed for today's London derby after sustaining a knock in training.
Reece James and Ben Chilwell both returned to the matchday squad for last week's clash with Fulham as Potter's squad continues to get stronger. The Blues remain without Armando Broja, N'Golo Kante, Edouard Mendy and Christian Pulisic, with Wesley Fofana having returned to full training this week as well.
