"We want to keep the strongest players".
Meeting the media for the first time since his appointment last week Sarri was, as expected, asked a series of questions about what he hopes to achieve in English football while with the Stamford Bridge outfit.
President Florentino Perez has been keen on signing the 27-year-old who has been a staple of Chelsea's success since joining in 2012 for the last couple transfer windows.
He paid tribute to his compatriot, while also saying he will need time to impose his methods, particularly with many players still absent after the World Cup. "I am very willing to work hard because it is going to be a difficult challenge but I am pleased to be here, and to work hard with Maurizio to be successful".
"Antonio has reached incredible results here and elsewhere", Sarri said, speaking through a translator.
"Clearly I play in a slightly different way so it will take some time for the squad".

Hazard has also previously said he would wait for clarity over the future of former boss Antonio Conte before making a decision over his future.
Hazard had one of his best year's for club and country helping guide Belgium to their best finish in a World Cup, third, and although Chelsea did not finish in the top four, Hazard had a career year in front of goal, scoring 12 goals.
Sarri, whose methods are admired by title winners Manchester City's manager Pep Guardiola, said he would not go into the discussions he had had with Abramovich, who has recently been embroiled in a visa dispute with the British authorities.
"I am an extremely open person, I do not have these kind of problems, I hope I will show this when I am working here and living here".
"They (Chelsea) have just asked me to build a season to be competitive in all competitions". "Obviously, with this World Cup, I think what was on the table is different than what I can have. Then during the season we'll see whether or not we want to have more specific objectives".
"For me it is an fantastic thing", he told Chelsea's official website on Wednesday night.
