It was another miserable night for West Ham in the London Stadium as Slaven Bilic's side slumped to a 3-0 home loss.
The result leaves the Hammers fourth from bottom and jsut two points off the dropzone - having played a game more.
Bilic did not hang around at the end of the match - disappearing down the tunnel as fast as West Ham fans streamed out the stadium following the Seagull's third goal.
A pair from Glenn Murray, his first in the top flight since 2015 - and a Jose Izquierdo wonder strike did the damage.
And while veteran Murray led the line superbly - no one in the West Ham ranks managed to shine.
Here's how the players rated...
WEST HAM UNITED
Joe Hart
Hammers keeper could do nothing to stop Murray's header and Izquierdo's wonder strike. 6
Pablo Zabaleta
Could have got closer to Izquierdo for the second goal and gave away sloppy penalty which ended the game. 5
Jose Fonte
Was made to look second best by Murray and is struggling to find his best form for the Hammers. 5
Winston Reid
Normally West Ham's best defender but he lost Murray for the goal and failed to recover. 6
Arthur Masuaku
Bilic made a big call to recall him in place of Cresswell, but the move backfired as he struggled to make any impact. 5
Pedro Obiang
Recalled to the heart of the midfield but failed to stop Brighton's onslaught. 6
Cheikhou Kouyate
Never looked himself from the opening whistle and was taken off at half-time. 5
Manuel Lanzini
Must be wishing he was still on the sidelines. Should have scored from close-range but never provided any kind of service. 6
Michail Antonio
The Hammers best player and that is saying something. Faded in second half but could not be blamed for shocking defeat. 6
Marko Arnautovic
Awful display from the Hammers club record signing. Booed by home fans when he was substituted. 3
Javier Hernandez
Failed to get any kind of service and only had one shot on target. 5
Subs: Ayew (46, 6), Fernandes (74, 6)
BRIGHTON & HOVE ALBION
Matthew Ryan
Comfortable evening for the Brighton keeper who was never tested by the Hammers attack. 7
Bruno
The Brighton skipper led by example and steered his side to an emphatic victory. 8
Shane Duffy
Commanding display at the heart of the Brighton defence. Never allowed Hernandez a sniff at goal throughout the ninety minutes. 8
Lewis Dunk
Emphatic display and is forging a solid partnership with Duffy at the heart of the defence. 8
Gaetan Bong
Was tested by Antonio in the first half but kept his composure to keep the Hammers forward off the scoresheet. 7
Anthony Knockaert
Clearly enjoying life in the top flight and can only grow stronger following this impressive display. 8
Dale Stephens
Solid display in the Brighton midfield and provided plenty of service for Murray and the Brighton forwards to cause so much damage. 8
Davy Propper
Never allowed West Ham's midfield to get anywhere near the Brighton box and and played a big role in the victory. 8
Pascal Gross
Lively throughout and was unlucky not to get on the scoresheet. Linked up well with Murray and played the perfect ball in for Murray's opening goal. 8
Jose Izquierdo
Fired an unstoppable shot past Hart into the roof of the net and was a constant threat to the Hammers defence. 8
Glenn Murray
Experienced forward turned back the clock to produce a stunning display and was rewarded with two goals. 9
Subs: March (69, 6), Schelotto (83, 6)
