Chelsea made an emphatic return to the Champions League and may have discovered a new cult hero.
Davide Zappacosta marked his home debut with an outrageous goal. In truth, it was a fluke and yet it lifted Stamford Bridge and stunned Qarabag, the minnows from Azerbaijan.
His strike was the second of the night and he was still charging up the flank to create the sixth for Michy Batshuayi in the closing minutes.
Pedro Rodriguez soothed Antonio Conte’s nerves with a fifth-minute opener and Cesar Azpilicueta nodded in the third, soon after the interval.
Tiemoue Bakayoko, on as a substitute, scored his first Chelsea goal with the help of a deflection and Batshuayi helped himself to a couple as the visitors from Azerbaijan wilted.
More importantly for Conte, here was a fourth successive victory since the shock defeat against Burnley. The Premier League champions are gathering momentum, a commodity he values highly.
Meanwhile, Manchester United made a return to the champions league with a three nil win over Basel in the first leg of the champions league group stage matches.
Substitute Marouane Fellaine gave United a first half lead before Romelu Lukaku and Marcus Rashford added two more goals after the break.
Elsewhere, Barcelona earned their revenge over Juventus as they thrashed them three nil thanks to goals from Lionel Messi and Ivan Rakitic, Paris St. Germaine beat Celtic Five nil, while Bayern Munich beat Anderlecht three nil.
AS Roma and Atletico Madrid settled for a barren draw.
