Chelsea boss Antonio Conte is confident of more from his players after their 3-0 rout of Burnley.
Eden Hazard inspired the Blues to a thumping 3-0 victory over Burnley to make it three wins out of three.
But Conte said: "In this game we started well and played good football the whole game, but we know we can improve and we must improve.
"It's a pity now that we have this international break because after three wins I want to continue to play games. But we have to stop.
"It's important to start in a good way. Usually when a new manager arrives he brings his method of football and new ideas, and you can have good ideas but it's also important to have results, so to start in this way is good for me.
"To start the season with three wins, and a win in the cup, is good for the confidence of the players and the fans, and me. I see a lot of positive things but we can improve."
