Chelsea boss Antonio Conte declared his side's title defence was over after Saturday's defeat at West Ham, but his players responded and goals from Tiemoue Bakayoko, Willian and Pedro secured
them victory at a canter.
Paco Alcacer had already given the hosts the lead
at the Camp Nou, and the leaders went on to
canter to a routine
victory against an Athletic side grateful they were not more soundly beaten.
