Match ends, Liverpool 1, Chelsea 2.
Eden Hazard scored a stunning late winner as Chelsea came from behind to end Liverpool's perfect start to the season and their hopes of winning the Carabao Cup.
Belgium international Hazard was introduced as a substitute in the second half and although he was quiet for much of it, burst into action by beating Alberto Moreno and smashing a finish into the far corner.
The Blues had been the better side in the first half with striker Alvaro Morata somehow striking a shot across the goalline and the Spaniard also nodded a free header over the crossbar.
Premier League leaders Liverpool, who had won all seven games this season, took the lead through Daniel Sturridge's well-executed hooked finish, just minutes after the England international missed a completely open net.
Chelsea levelled the contest through Emerson Palmieri's close range finish which needed intervention from the video assistant referee (VAR) to check for offside before being awarded.
Liverpool will be looking for revenge when the two sides meet against in the league on Saturday (kick-off 17:30 BST), while the fourth-round draw takes place on the same day at 21:00 BST.
