Enzo Maresca's side took the lead in the fourth round tie as early as the fifth minute when Bart Verbruggen somehow bundled a tame Cole Palmer cross into his own net. However, the Seagulls - who were thumped 7-0 by Nottingham Forest last time out - did not fold and were level seven minutes later thanks to a brilliant header from Georginio Rutter.
Rutter turned provider for Brighton’s winner as Kauro Mitoma produced a clever finish in the second half to knock Chelsea out and spark jubilant scenes from the home supporters inside the Amex Stadium after the final whistle.

7 min: That is a Grade A goober. He does absolutely everything wrong, Verbruggen. His positioning is poor, with too much goal exposed, then he reads both the flight and the direction of the cross wrong, but even then he’s under not sort of pressure and just bundles it in.

Boos for Robert Sanchez, boos for Marc Cucurella and I’m sure there will be for Moises Caicedo when he gets on the ball, too. They’re in for a busy night, the home crowd.

FA Cup rule change
The FA Cup rules have changed this season. Replays have been scrapped from the first round onwards, with a winner determined on the day of the ties.
So, if the scores are level after 90 minutes tonight, a period of 30 minutes of extra time will be played with a penalty shootout to follow if a winner can not be found in that time.
