"You can see that in our preseason, in every friendly game I played the best formation and it happened also today, because my choice was to put the players we have in this moment".
The story of the match was nearly encapsulated in the first few minutes of play when Marcos Alonso's reckless challenge was punished with a yellow and Ben Mee headed straight at Thibault Courtois from the ensuing free kick.
Most people were expecting a relatively comfortable afternoon for the champions but their task got a lot more hard when Gary Cahill was shown a straight red card for a studs-up challenge on Steven Defour in just the 14th minute.
Burnley opened the scoring thanks to a scrappy goal from Sam Vokes, which deflected off David Luiz, before doubling their lead through an anything but scrappy volley from left-back Stephen Ward. Vokes, standing just behind him, beat Thibaut Courtois with a faint contact that dribbled perfectly into the far corner. I'm very proud for this but today I saw two faces: "one positive in the second half and one negative in the first half".
Antonio Conte gave Alvaro Morata 31 minutes from the substitutes' bench on his Premier League debut and he scored with a header. Alonso had a fierce free kick well saved by Tom Heaton just after the hour mark. David Luiz pulled back another to make it 3-2 and draw a roar of defiance around Stamford Bridge.
Conte will have some thinking to do, along with the board, as both Cahill and Fabregas will be missing for next week's match with Tottenham Hotspur.
Chelsea went down to nine men via a red card to Fabregas with about 10 minutes to go.
Stamford Bridge is never an easy place to grab a result, but Sean Dyche's men are making it look effortless against a 10-man Blues squad after they had Gary Cahill sent to the showers early after a cynical challenge.
The victory was Burnley's first on the opening day of the top flight in 44 years, and it comes after they had to wait until their 18th away game to record a first success on the road last season.
