Brighton & Hove Albion's Leandro Trossard celebrates scoring their first goal.
But the hosts made a blistering start at the Amex Stadium against Potter’s bewildered side, racing into the lead inside five minutes through a well-taken Leandro Trossard goal. Pascal Gross’s last-gasp fourth goal capped a fine afternoon for Potter’s successor Roberto De Zerbi, with the first win of his reign moving Brighton up to seventh in the standings, while Chelsea stay fifth, eight points behind leaders Manchester City.
Determined to make an impression against the man he succeeded in the Brighton managerial hotseat, De Zerbi set his team up to attack from the off. Connor Gallagher should have got Chelsea back into the game before Chalobah’s unfortunate attempt to clear the low cross went wrong, but the England midfielder made amends when he expertly set up Havertz for Chelsea’s goal.
