Estevao scored a 95th-minute winner to earn Chelsea a 2-1 victory and inflict a third consecutive defeat in all competitions on English Premier League Champions, Liverpool.
Liverpool were looking to bounce back from losses to Crystal Palace and Galatasaray having been knocked off top spot in the Premier League by Arsenal following their win over West Ham on Saturday.
However, the Reds were deservedly beaten when the Brazilian teenager Estevao turned home in added time, sparking wild scenes at Stamford Bridge, including from head coach Enzo Maresca, who was sent off for running down the touchline to celebrate with his players.
Arne Slot’s side had to come from behind after Moises Caicedo blasted Chelsea ahead in the 14th minute with an unstoppable shot from the edge of the box that crashed into the top left corner.
Cody Gakpo delivered the equaliser in the 63rd minute when Alexander Isak’s touch from Dominik Szobozlai’s cross fell into the path of the forward to stab in.
Chelsea had the better of the first half, although struggled initially at the start of the second as their problems at centre-back continued with both Benoit Badiashile and Josh Acheampong forced off injured.
Florian Wirtz came on at half-time and lifted Liverpool, albeit only momentarily, with Mo Salah wasting two good opportunities before Chelsea finished much stronger.
