Chelsea boss Antonio Conte has said that he has demanded improvements from his side despite winning each of his three games in charge of the club.
After two narrow wins in the Premier League, Chelsea were tested by Bristol Rovers in the EFL Cup on Tuesday night before they eventually ran out 3-2 winners at Stamford Bridge.
Newly-promoted Burnley are the visitors to West London on Saturday afternoon, and Conte has admitted that he is expecting another "difficult" test.
The 47-year-old told reporters: "Every game is very tough in England, you must understand anything can happen. We saw that against Bristol Rovers. We've played three games and won them all but I've told my players we can improve a lot, that's logical.
"Burnley will be very difficult. They are very solid and always ready to counter-attack with two good forwards."
Chelsea are one of four teams who head into this weekend's fixture with a 100% record in the top flight.
