Brighton sign defender Webster from Bristol City in club-record...
Brighton fans had invaded the pitch at the end of their game to celebrate their return to the top flight after a 34-year absence.
A run of five straight wins came at just the right time for Brighton, who agonisingly missed out on automatic promotion last season after finishing third and failing to get through the playoffs.
"I’m incredibly proud of the way that they bounced back. To put together the run they have, at this stage of the season, is incredibly difficult, and they deserve every bit of credit," Brighton manager Chris Hughton said.
"I knew we had a group of lads that were capable of doing it, but being capable of doing it and actually doing it are two different things.
"They’ve been good all season. They’ve bounced back and shown good determination and desire to win as many game as possible. It is a wonderful achievement," he added.
