Defender Gary Cahill says discipline, organisation and keeping fit are three things new manager Antonio Conte has brought to Chelsea this season.
The Blues have won all their first three games in the English Premier League, confirming that they will fight for the title against the likes of Manchester City and Manchester United.
The Englishman was delighted after Saturday's 3-0 win against Burnley and praised Conte for giving vital instructions to his players.
"It was a very convincing win, I felt we played well from start to finish and totally dominated the game," Cahill told the club's official website.
"Burnley got a fantastic result last week so they were in high spirits and full of confidence but we totally dominated the game and it was a great result before the international break.
"We've added one or two quality players which is great but predominantly it's the same players from last year, and when we won the league the season before.
"The main thing for me is how fit and sharp we look, and the organisation in terms of where players need to be. I felt like last year we were all over the place at times.
"We've got discipline, we're organised and we look fit. I'm in the best condition I've been for a long time.
"The manager is adamant about the way he wants to play and that's what everyone has to buy into. If everybody pulls in the right direction, nine out of 10 times you'll succeed.
"The fitness and nutrition, things that people probably don't see, is vitally important, especially in this league."
