Nine-man Crystal Palace clung on to a 2-1 lead through 12 minutes of second-half added time at Selhurst Park to secure their first league double over arch-rivals Brighton in 92 years.
Jean-Philippe Mateta fired the hosts in front three minutes in, but Danny Welbeck drew the sides level before the break, surpassing Pascal Gross as Brighton’s top Premier League goal-scorer in the process.
Daniel Munoz put Palace back in front 10 minutes after the restart before both Eddie Nketiah and Marc Guehi were sent off with second yellow cards.
It was briefly nine versus 10 when Jan Paul van Hecke was also sent off with a second booking in the sixth minute of second-half added time.
