Chelsea confirmed Sarri's appointment on Saturday after more than a month of hard negotiations with Napoli, and swiftly followed that announcement by completing a reported £50 million deal to bring Italy global playmaker Jorginho to Stamford Bridge.
Major trophies have so far proved elusive for Sarri in his 13-year coaching career, but he insisted that he is driven to bolster his growing reputation with silverware at Stamford Bridge.
Antonio Conte has expressed gratitude to his "friends" at Chelsea for "two unforgettable seasons" which ended with his acrimonious sacking last week. "I have made many memories during my time with Chelsea, which I will take with me into my next challenge", explained the Italian coach.
Sarri's appointment was confirmed on Saturday morning, and he said that he is looking forward "to starting work and meeting the players".
Antonio Conte has released a statement thanking Chelsea's staff for their "hard work and support" during his time at the club.

Olivier Giroud looks like being the first casualty of new Chelsea chief Maurizio Sarri's reign.
Sarri will be followed to West London by Napoli's Brazilian-born Italy global midfielder Jorginho, whose signing was also confirmed on Saturday by the Roman Abramovich-owned club.
Chelsea are already a week into their pre-season training, but the 59-year-old is eager to get started in his new post.
Conte won the Premier League title in his first season in charge and backed that up by winning the FA Cup last season. Reports of dressing room bust-ups and discord with Roman Abromovic after a disappointing Premier League season saw his side finish fifth, bolstered rumours of his departure.
Jorginho was a deep-lying playmaker in Sarri's Napoli team that finished second in Serie A last season and played some of the best football in Europe.
