Joao Felix was named in injury-hit Chelsea's starting line-up, a day after joining on loan from Atletico Madrid, and saw red for a lunge on Kenny Tete shortly before the hour mark.

Chelsea had fought its way back into the match at the time of that dismissal after Kalidou Koulibaly's close-range finish cancelled out former Blues winger Willian's first-half opener at Craven Cottage.

Fulham was without suspended top scorer Aleksandar Mitrovic, but Carlos Vinicius headed in his first Fulham goal in the 73rd minute to land his side a rare win in this fixture and make it six defeats in eight for Chelsea.

Bernd Leno did well to keep out an early Lewis Hall strike in a bright start from Chelsea, with Joao Felix looking particularly lively in the final third.

Fulham soon grew into the game and struck the crossbar through a powerful Bobby Decordova-Reid effort, shortly after Carlos Vinicius had a penalty shout rejected.

However, Willian gave Fulham the lead when Chelsea's defence backed off and allowed the winger to fire away a shot that deflected off Trevoh Chalobah on its way through.

Leno continued to frustrate Chelsea, but he was almost caught out by a Mason Mount free-kick that struck the right-hand post and landed nicely for Koulibaly to squeeze over the line.

Chelsea lost another player to injury when Denis Zakaria hobbled off and then had Joao Felix dismissed for a studs-up challenge on Tete.

More misery was to follow for Chelsea and Potter as Andreas Pereira played in a delightful cross for Carlos Vinicius to get above Chalobah and power home a winning goal at the back post.
