Reece James aggravates knee problem on return to action

Chelsea boss Graham Potter is concerned that Reece James has suffered a recurrence of the injury which ruled him out of the World Cup.

England full-back James looked distraught as he received treatment on the same knee he injured in October during Chelsea's 2-0 win over Bournemouth.

Bournemouth had won on three of their last five visits to Stamford Bridge, but despite some late pressure on the Chelsea goal they never
