Alireza Jahanbakhsh scored with a spectacular overhead kick to stun Chelsea and earn Brighton an unlikely point at the Amex Stadium.
The Seagulls were poor for most of the match and looked set for defeat before the Iranian substitute, who scored his first goal for the club on Saturday, brought the home support to their feet in the 84th minute with an early contender for goal of the month.
Cesar Azpilicueta gave Chelsea the lead with his third of the season when he fired in from close range after Tammy Abraham’s shot was blocked by Aaron Mooy.
Brighton’s attacking threat was largely nullified by Chelsea’s defence, although aside from the goals they produced the clearest chances – both thwarted by the brilliance of keeper Kepa Arrizabalaga.
The Spaniard produced a one-handed stop to deny Aaron Connolly and then saved Neal Maupay’s low drive with his feet.
The point extends fourth-placed Chelsea’s advantage over Manchester United in fifth to five points. Brighton move up a place to 13th, above Burnley on goal difference.
