ENZO MARESCA was sent off after running down the touchline after Estevao's late winner against Liverpool.
The Brazilian proved to be the hero from the substitutes bench as he tapped in Marc Cucurella's cross in the 95th minute.
It sparked bedlam inside Stamford Bridge with Maresca tearing off to join in the celebrations.
When he returned to his dugout the Italian was greeted with a yellow card - his second of the match.
His sending off means Maresca will now serve a suspension.
So assistant boss Willy Caballero will take charge of Chelsea's next game againt Nottingham Forest.
Maresca will likely not care too much after the dramatic win over title favourites Liverpool.
He had been under a bit of pressure ahead of kick-off following back-to-back Premier League defeats.
Chelsea's task was also made more difficult following the second-half injuries to Benoit Badiashile and Josh Acheampong.
That left the Blues with just one fit centre-back, Jorrell Hato, with Reece James filling in as a makeshift partner.

Chelsea were without several key players including Cole Palmer, Liam Delap and Trevoh Chalobah.
They are now down to just two fit centre-backs - Hato and Axel Disasi, who is a member of the bomb squad.
