A second half Nicolas Jackson goal gifted Chelsea a place in the forth round as well as their first win against Brighton in more than three years.
Both clubs fielded strong sides, with Roberto De Zerbi making seven changes to his starting-11, and Brighton’s best chance came in the second half when their former shot-stopper Robert Sanchez blocked Solly March’s header.
