Chelsea produced a superb performance to brush Barcelona aside in their marquee Champions League clash, with Enzo Maresca's side running out comfortable 3-0 winners.
The Blues had seen two goals ruled out in the first half before a Jules Kounde own goal gave the hosts a well deserved advantage.
Barcelona were reduced to 10-men late when Ronald Araujo was shown a second yellow card for a clumsy foul on Marc Cucurella in the closing moments of the first half.
Chelsea's rising Brazilian star Estevao produced the moment of the night with a slaloming run and powerful finish in the 55th minute.
