Fulham increased more pressure on Chelsea boss Graham Potter as the new Blues forward Joao Felix was sent off on his debut in their 2-1 defeat at Craven Cottage. Potter's troubled side crashed to a seventh defeat in their last 10 games in all competitions after another spluttering display. Chelsea fell behind to a goal from their former winger Willian in the first half at Craven Cottage on Thursday. Kalidou Koulibaly equalised after the break but a rare mistake by Chelsea goalie Kepa handed Fulham the win as the Blues suffered yet another defeat under Potter.
