Overview

• Chelsea led through Enzo Fernandez before Trevoh Chalobah was sent off in the 53rd minute, and Brighton overturned the match with a Danny Welbeck brace and a Maxim De Cuyper header in stoppage time.
• Maresca said Chelsea “cannot continue to give away presents,” linking the defeat to discipline issues after last week’s early red card for goalkeeper Robert Sanchez at Manchester United.
• Co-owner Behdad Eghbali and senior recruitment chiefs went to the dressing-room area post-match, which Maresca said was routine and did not involve addressing the players.
• Injuries have depleted Chelsea’s centre-back options — including Levi Colwill, Tosin Adarabioyo and Wesley Fofana — and Chalobah’s dismissal triggers a suspension for the Liverpool game.
• BBC Sport reports Maresca will be judged on qualifying for the Champions League; Chelsea have eight points from six league matches and now host Benfica before facing Liverpool.
