Scroll down and click through to see who shone and who struggled for Graham Potter's men against big spending Chelsea.
5. Webster 6/10
Played left side of the defensive trio and looked pretty comfortable. Tried to move the ball forward when could and one long range effort whistled over. Unlucky to deflect Chelsea's third into the net
6. Bissouma 6/10
Bright start and drove forward well and snapped into tackles. Turning into Brighton's main man in the central midfield area but overrun in the second half by the power and class of Chelsea
7. Alzate 5/10
Gave the ball away in midfield for the opening goal. Had been playing well up until that point but didn't feel sorry for himself. One stinging first half effort saved well. Replaced by Jahanbakhsh with 10 to go
8. Lallana 5/10
Pressed the Chelsea defence well and trademark quick feet and close control in tight areas. Promising start but hobbled off just before the break, which is a worry considering his injury problems
