Fulham manager Marco Silva hailed “a great night for the club and the fans” as his side beat 10-man Chelsea in a fiery west London derby at Craven Cottage.
Carlos Vinicius headed in a 72nd-minute winner after Portugal winger Joao Felix had been sent off on his Chelsea debut when the score was 1-1.
Willian put the hosts ahead against his former side in the first half, before Kalidou Koulibaly equalised early in the second, but Vinicius’ winner saw Fulham move up to sixth in the Premier League.
“Chelsea is a super team, they are a massive club and their budget is completely different to ours, you can’t compare,” said Silva.
“It was a great night for our fans and they deserved it. For our football club, for our fans it’s special and I definitely felt it at the final whistle – the way they celebrated was a really important moment.
“Our players have been brilliant for the season so far but we know we are just in the middle of the season and as a manager there’s big room to improve.”
Chelsea’s defeat increases the pressure on manager Graham Potter with the Blues now having won only twice in 10 matches in all competitions.
Joao Felix, who only joined Chelsea on Wednesday in a £9.7m loan deal until the end of the season from Atletico Madrid, was shown a straight red card for a horrible lunge on defender Kenny Tete after 58 minutes and will now be suspended for three matches.

Potter’s Blues side started brightly, but the hosts nearly took the lead when Chelsea lost possession and Vinicius played a pass through to Bobby de Cordova-Reid, who fired against the crossbar with Kepa Arrizabalaga beaten.
But Chelsea fell behind two minutes later in the 25th minute.
It was poor defending from the visitors as teenage left-back Lewis Hall failed to clear, before Trevoh Chalobah should have done better with his clearance.
The ball fell to Willian and the Brazil midfielder, a two-time Premier League winner during a seven-year spell at Chelsea, saw his strike take a big deflection off Chalobah to give Arrizabalaga no chance. Willian did not celebrate against his former team.
But Chelsea equalised within two minutes of the second half as Koulibaly reacted quickest to force the ball over the line from close range after Mason Mount’s free-kick had bounced off the left-hand post.
Joao Felix had been the visitors’ best player before his dismissal left his side on the back foot and the 10 men duly conceded the winner to Vinicius.
