"Guardiola told me here in England that it is very hard, the level is very high", said Sarri, who declared his desire to remain at Chelsea for a decade. "I stay here because I think we can improve, but to get more than 100 points - no".
However, Italy global Jorginho followed Maurizio Sarri to Sunday's Community Shield opponents Chelsea, and Guardiola is ready to give a chance to 20-year-old Brazilian Luiz, who joined from Vasco da Gama in a £10 million move last summer.
Chelsea have lost each of their last two games against Manchester City - they haven't lost three in succession against them since September 2010.
Manchester City take on Chelsea in Sunday's Community Shield - the traditional curtainraiser to the English season - but the Wembley showpiece will offer few clues as to the destination of the Premier League title.
"The way he plays, I think will be flawless for English football". Antonio [Conte] was, Maurizio will be too.
A high-octane set-up and such an adjustment to their work under Antonio Conte means Chelsea's players are likely to need more time to adapt to Sarri's attempts to bring a thrilling style.
Hope dances in Drake In My Feelings video
It's unclear at the moment if Shiggy himself will make a cameo in the video or not, but we'll know in a matter of hours if so. Drake has dropped the video for his viral track In My Feelings - and BTS fans should probably watch it all the way to the end.
One man Guardiola and his charges will be up against on Sunday is Italian midfielder, Jorginho who shunned the Citizens to link up with the Blues.
City are also without a number of key players following their World Cup exploits but Guardiola will want to be successful and keep the winning feeling flowing heading into the new campaign.
"Yes, we were close, but in the end Jorginho made a decision to stay with Sarri", Guardiola said. Antonio (Conte) was. I am delighted that players with this style of play will be flawless for English football. He didn't want that.
"Maybe it was a bit late to announce that, but if you don't want to come, don't come, and good luck with Chelsea". And Mahrez could find himself on the scoresheet against Chelsea, with Guardiola having stated he is expected to overcome a minor fitness issue. Nobody put it in his head to come.
Alexis was heavily linked with City in January after failing to join last summer but eventually signed for their neighbours, Manchester United.
