Brighton defender Adam Webster hailed the home support for Saturday's thumping win against Chelsea.
The Seagulls won 4-1 at Falmer stadium to deliver Blues manager Graham Potter a miserable return.
Webster said, "It was among the best atmospheres I have experienced. Seeing the fans jumping around after the final whistle was incredible.
"If we can create such an atmosphere in future matches, it can make a big difference.
"They made it a horrible place to visit for an away team, and although it's a cliché, they were our 12th man."
