New signings Diego Costa and Cesc Fabregas made an instant impact for Chelsea as they launched their Premier League title bid with a confident 3-1 win at promoted Burnley.
Former Arsenal midfielder Fabregas, brought in from Barcelona during the close season, was influential throughout the game, having a hand in all three Chelsea goals and striking up an impressive midfield pairing with Eden Hazard.
Chelsea recovered from conceding a 14th-minute goal, quickly turning on the style in an impressive half hour spell to go in 3-1 up at the break.
Jose Mourinho's side were content to see out the game in the second half as Burnley, tipped by many for relegation, put in a creditable professional display after the Londoners had threatened to run away with the game.
"I think we had a good reaction and the first part of that is that emotionally we were not affected by the goal we conceded," said Mourinho.
"We kept playing according to the way we want to play, the players were calm and never lost their composure and after that we had a fantastic 20-25 minutes with three goals, the second one a fantastic goal, and in the second half we had control of the game."
