N'Golo Kante is excited rather than daunted at the prospect of playing under new Chelsea manager Maurizio Sarri this season.
Willian was not satisfied regarding Antonio Conte's coaching.
Conte also banned a wide selection of foods in the training ground canteen and also in hotels when the club travelled for away games.
Sarri's new system seemed to bring out the best in Kante, who played in a much more advanced role.
World Cup winning star N'Golo Kante got the Blues started in the 34th minute through a close range jab into the net.
Trump Trolls Democrats: ‘Please Do Not Distance Yourselves From Nancy Pelosi’
The sarcasm-dripping tweet aside, Trump's interest in Democrats backing the House minority leader is likely genuine. NBC News on Friday released a list of 51 such candidates and incumbents who have said they will not support Pelosi.
The new Chelsea manager has abandoned the practice of the squad staying together at the Chelsea Harbour hotel on nights before they have an evening game at Stamford Bridge the following day, a measure that was introduced by Conte and was unpopular with numerous players.
"That's why Sarri talked about "fun" football because he wants to build from the back". This is what we will try to do this season.
But his desire to play on the front foot has already endeared him to Willian after two seasons under Conte's rigorous tactical approach that prioritised making Chelsea hard to beat.
Chelsea's next fixture is against Arsenal this Saturday.
Chelsea welcome London rivals Arsenal to Stamford Bridge on Saturday evening and we've got some early team news ahead of the game. "Now we have a different style, that's why we can create problems for Arsenal".
Speaking to reporters (via ESPN) Willian said: "I'm here". I think we played very well.
