Chelsea tasted defeat in the Premier League for the first time this season, as they were stunned with a 3-1 scoreline at Tottenham.
Mauricio Pochettino's side leapfrog them to go third in the process, with a performance that showcases their own potential to challenge Manchester City and Liverpool at the top of the table.
Goals from Dele Alli and Harry Kane put them two up inside 16 minutes and Son Heung-min made it three after the break with a brilliant solo goal.
It was a 10th win from 13 games this season for Mauricio Pochettino's men and the rampant showings of Kane, Alli, Son and Christian Eriksen will have the Argentinian licking his lips at the prospect of what might be to come.
They could have won by a far bigger margin had it not been for some wayward finishing and some impressive saves from Kepa Arrizabalaga.
Chelsea were a shadow of the side that had not tasted defeat in their opening 12 league games, though did bag a late consolation through Olivier Giroud, and Sarri will now have to contemplate his first loss in the Blues dugout, having only previously lost in the Community Shield against Manchester City.
