Scroll down and click through to see who shone and who struggled for Graham Potter's men against big spending Chelsea.
1. Maty Ryan 6/10
Crashed into Werner to concede the first half penalty and was sent the wrong way from the spot by Jorginho. Sharp save to deny Werner at the near post. Could do nothing with James's strike and wrong footed by a deflection for the third
2. Lamptey 8/10
Blistering pace really helps Brighton defensively and in attack. Great challenge on Alonso early on and grew in confidence from there. One brilliant cross for Maupay in the first half. Good display against his former club.
3. White 7/10
A very classy PL debut from the 22-year-old. Good on the ball and one fine intervention to thwart Loftus-Cheek on the counter. Hobbled off with 10 to go after another important challenge on Werner, which is another injury worry for Albion
4. Dunk 6/10
Missed a golden chance to draw Albion level when the scores were 2-1 but he headed wide from close range. Didn't place a foot wrong defensively
