The youthful Chelsea side, managed by Enzo Maresca, delivered a commanding performance, marking a significant moment in his 18 months at the helm.
Goals included an outrageous individual effort from Brazilian teenager Estevao and a debut home goal for £30million summer signing Liam Delap.
Delap praised the team's execution of their game plan, stating they are “getting better and better, "building something really good" and can perform against any opponent.
This superb showing revitalises Chelsea's Champions League campaign, making direct passage to the last-16 likely with two more wins from their remaining three league phase matches.
