Graham Potter’s blues side Chelsea started brightly in their match against Fulham but they fell behind two minutes later in the 25th minute when Willian Borges came up to score his former employees.
Chelsea equalized with in two minutes of the second half as Koulibaly reacted quickest to force the ball past the line from close range after Mason Mount’s free kick hit the left post.
Graham Potter’s men came into the fixture looking to ease the pressure on themselves after a string of disappointing results in recent weeks.
Joao Felix, who only joined Chelsea on Wednesday in a £9.7million loan until the end of the season from Atletico Madrid was shown a straight red card for a horrible takle on defender Kenny Tete after 58 minutes and will now be suspended for three matches.
Joao Felix had been the visitors’ best player before his side on the back foot and the 10 men duly conceded the winner to Vinicius as Fulham’s excellent season continues.
Fulham moves up to the sixth position on the premier table, although they have played two more games than Liverpool which they moved above after yesterday’s game. The blues find themselves placed tenth in the premier league after a number of disastrous performances this season.
