Speaking after the clash, Brighton manager Roberto De Zerbi claimed Brighton were the better side.
De Zerbi told BBC Match of the Day: “It is hard because I think we played much better than Chelsea.
“We made three big mistakes, two set pieces in the first half and we conceded the third goal in an incredible way.
“It was a clear penalty for them [for the game-winner] but we can’t concede a counter-attack in that way. A corner for us. In that way we are young but we need to be more focused in that situation, a set pieces.
“We lost the game from that situation, not from the play because we played a great game. But football is like this.”
Meanwhile, Mauricio Pochettino while sharing his post-match thoughts on Chelsea’s 3-2 home with against Brighton, claimed Chelsea played better before the red card.
“We deserved the victory because when you analyse the game, we played the game that everyone expects from us,” he told Sky Sports.
“We were very competitive. This game was all about the win. We had one player less for more than 60 minutes.
“It’s an important victory for us, because after Newcastle, we needed to show a different face, and the team’s response was really good.”
