Brighton manager Graham Potter to BBC Sport: "The performance was good in many aspects; we more than matched Chelsea for long periods. I'm disappointed with the opening goal, but errors can happen. We were heavily punished with a wonder strike - and ultimately, if you concede three times it's hard to win football matches.
"You have moments against the big teams that you need to have go your way and we need to learn from that. But there are positives. Adam Lallana was enjoying the game, he brings that personality, we are pleased with what he has brought to us and we just have to help him get on the field more often."
Chelsea manager Frank Lampard to BBC Sport: "To come to Brighton and win is a tough ask. We've only had a few days, so I didn't expect the kind of football we want to play. We had to do some of the more difficult things - resilience, throwing yourself in front of the ball, so I'm pleased.
"We've had a lot of quarantines, a lot of players who aren't match fit. That's how this season has started. There's a lot of strain on these players and hopefully we'll get better and better."
