Davide Zappacosta's stunning first-half strike set Chelsea on their way to an emphatic win against Azerbaijani side Qarabag on their Champions League return.
The Italian, bought from Torino in a £22.5million deal, said: 'It was a dream debut.' Pedro, Cesar Azpilicueta, Tiemoue Bakayoko and a brace from Michy Batshuayi completed the rout.
Meanwhile, Chelsea manager Antonio Conte insists he will not risk Eden Hazard's fitness ahead of Sunday's crunch London derby against Arsenal.
The Belgium international took another significant step towards full fitness after suffering a broken ankle at the end of last season in the win over Qarabag, coming on as a 58th minute substitute to add to the 12 minutes he played against Leicester on Saturday.
