New head coach Maurizio Sarri has said that his Chelsea players must "enjoy themselves" in order to perform to the best of their ability.
On Saturday, Chelsea confirmed that Sarri had replaced Antonio Conte in the dugout, and the immediate challenge will be to earn a return to the Champions League for the 2019-20 campaign.
To achieve that, Sarri has suggested that his team must be participating in a "fun" environment, something that the Italian will look to bring to the West Londoners.
Via the club's new app, Sarri said: "In Naples I was very lucky to find my players adapted to my way of football. They were strong as players, and strong from a human point of view. I was lucky to transport my idea of football onto the pitch, with the quality of these players.
"The players have to enjoy themselves. First of all, I hope the fans can enjoy the team. I want to bring enjoyment to the fans, the fans have to be proud of the team. 100% hard work and 90% fun.
"It is impossible in my job to promise something else but I will surely give all in my possession to win something with Chelsea."
Chelsea have already added Napoli midfielder Jorginho since Sarri's arrival at Stamford Bridge.
