Reece James' injury is far from ideal for Chelsea and Graham Potter. football.london understands that James' knee problem picked up in the win over AC Milan on Tuesday is worse than first feared.
It makes the 22-year-old a doubt for the World Cup and he is due to see a specialist over the weekend. It's a huge blow for James, who has arguably been the Blues' best performer so far this season.
He managed to keep Rafael Leao quiet over both games against Milan, while he also scored and claimed an assist in the clash against the Serie A champions at Stamford Bridge. There is definitely an argument to be made that he is one of Chelsea's most important players - and therefore his absence will be felt.
