It is only one game, yet the parallels with Chelsea's last defence of a Premier League title two seasons ago under Jose Mourinho were uncanny.
There had been a change of guard over the summer with John Terry's departure with Cahill taking the armband, but his league debut as permanent captain lasted all of 14 minutes. Boga, an exciting talent, had little time to make any sort of impact before becoming the unfortunate collateral damage of Cahill's early red, sacrificed for Andreas Christensen in the 18th minute.
Conte was without the injured Pedro and the banned Victor Moses, so Cesar Azpilicueta switched to right wingback, and Belgian Michy Batshuayi led the champions' attack.

But Rooney ended a scrappy first half when he headed in to mark his Goodison homecoming in the best possible style.
Antonio Conte did not see his side go down to 10 men once during his debut campaign in the English top flight. Disjointed and embarrassed in the first half, Chelsea threatened to mount the most unlikely of comebacks in a stirring second-half display, but just failed to overcome their numerical disadvantage.
At Stamford Bridge they exploited Chelsea's early red card brilliantly, intelligently picking the champions apart with inviting crosses.
Fabregas and Cahill will be suspended for Chelsea's tough second match of the season, away to Tottenham at Wembley Stadium next weekend.
Standing in their way of starting the new season in style is a Clarets side which won just once on their travels last season - in the penultimate away game against Crystal Palace - and have been weakened by the departures of Michael Keane and Andre Gray.
