Zappacosta making his first appearance for the Blues scored an absolute stunner to make it 2-0 within half an hour of play.
Goals from Pedro, Davide Zappacosta, Cesar Azpilicueta, substitute Tiemoue Bakayoko and a Michy Batshuayi double ensured a comfortable return to Europe's elite after last season's first absence since 2003-04. The fourth win in a row comes five days ahead of the visit of the Gunners in one of the defining top flight fixtures of any campaign.
The third goal gave Antonio Conte the chance to introduce Eden Hazard in order to step up the Belgian's recovery from a fractured ankle, but the attacker remained on the periphery of the game for much of the final half-hour.

Mr Ri and Mr Hong's roles have also been noted overseas, prompting the United Nations, the US and South Korea to blacklist them. The State Department's Thornton said Seoul had "come around very nicely" and appeasement not South Korea's policy.
Moses was left on the bench for the entire 90 minutes of the game. I think the 3-0 is a little bit against the grain of the game in this period. So who shall we see in a blue shirt? Qarabag is an unnoticed team which only played in the domestic matches. Otherwise we risk a bad injury to delay the situation. "This process is good for him". "And also to [Andreas] Christiansen".
"You know very well in this league there are six or seven teams ready to fight not only for the title, but also for a place in the Champions League and the Europa League". My message tonight was this: that I trust all my players not all with words but with facts.
Qarabag beat the champions of Georgia, Moldova and Denmark to become the first Azerbaijan side to reach the Champions League group stages. If we think we can play with 13 players like last season, we are insane. He is very good with and without the ball.
