The Blues, the clear title favourites with many fans and pundits this season, had to watch rivals Arsenal and Manchester City notch up 2-1 and 2-0 wins respectively, laying down the gauntlet for Chelsea - who had to wait until Monday night to get their season started against newly-promoted Burnley.
A shock looked to be on the cards when midfielder Scott Arfield gave the Clarets a shock lead in the opening 15 minutes, but then Jose Mourinho's side flexed their muscles with a dominant display from then on. Goals from Diego Costa, Andre Schurrle and Branislav Ivanovic handed Chelsea a 3-1 lead at half time, and they professionally saw out the game to notch a comfortable win.
The star of the show wasn't in any doubt. New signing Cesc Fabregas joined from Barcelona in a £30m deal earlier this summer, and his return to the Premier League couldn't really have gone any better. The Spaniard had a big hand in the first goal, before a stunning assist for Schurrle's goal and a pinpoint cross for Ivanovic gave him two assists at the break.
Already, this is a feather in the cap for Mourinho this season. He's done what his rivals wouldn't do - sign Fabregas.
The 27-year-old was a target for both Arsenal and Manchester United, only for Mourinho's managerial rivals Arsene Wenger and Louis van Gaal to snub the Spaniard when it came down to the crunch.
"We talked with Wenger but he said that he would find it difficult to make a place for me on the pitch as Ozil had my position covered," Fabregas said of Arsenal's interest, whilst it was reported that van Gaal cancelled a deal to sign Fabregas as he already had Juan Mata at his disposal.
Now, Arsenal and United fans are crying out for another midfielder to be brought in for their respective clubs, and Fabregas made a mockery of the notion that he could only play as an attacking midfielder with an outstanding display in a deep-lying role for Chelsea.
In a season and a title race which could be decided by the mind games played by Wenger, Mourinho and others, the self proclaimed 'Special One' has already landed the first blow by making his opposing managers regret passing on a player who looks like he's given Chelsea the missing ingredient in an already impressive team.
