Graham Potter had no complaints about Joao Felix's red card as he bemoaned losing another player.
The Blues boss saw his side lose for the third time in a week as they were downed by local rivals Fulham, who are now six points clear of Chelsea. Vinicius headed home the winner for the Cottagers, but only after the visitors went down to ten men.
Felix was signed on loan this week from Atletico Madrid and went straight into the starting XI. Chelsea have struggled for goals and the Portuguese forward will help them in the final third, but his impact will now be delayed as he was sent-off for a second-half lunge.
