For the first time in his 15-year reign at Chelsea, Roman Abramovich will be running the club from afar this season.

Following a dispute over his UK visa, the billionaire owner has become an Israeli citizen and is moving to Tel Aviv.

That said, he has already had plenty of Chelsea business to contend with this summer, not least sacking Antonio Conte and replacing him with Maurizio Sarri.

The former Napoli boss was officially unveiled earlier this week and while Abramovich immediately backed him with the signing of Jorginho, who looked as though he was headed for Manchester City, attention now turns to keeping hold of key players.

According to widespread reports, Real Madrid are stepping up their pursuit of Eden Hazard and Thibaut Courtois, with both players keen on the move.

Regardless of the squad he has at his disposal, Sarri has been installed because the board feel it is time to bring attacking football to west London.

However, The Sun report that as much as Abramovich wanted Sarri, he has already imposed some strict rules on his new manager as he expects a "British attitude" towards coaching from him.

What's expected from Sarri 

Specifically, the Russian has banned the Italian from smoking cigarettes in the dressing room at half-time and has instructed him to wear a suit on matchdays, both in the dugout and in front of the media.

At Napoli, the 59-year-old used to smoke on the touchline, until unsurprisingly the authorities put a stop to that. The Serie A club then installed a designated area in the dressing room for him to use at the interval.

Stamford Bridge will offer no such facility and unless he is willing to go outside the stadium - which would be tricky in 15 minutes - he will have to forego an element of his persona that made him so well-received in his former jobs.

Chelsea are focusing heavily on the practicalities of Sarri's move to England, ensuring all his assistants learn English and giving him a driving instructor to teach him to drive on the left-hand side of the road.

Fan favourite Gianfranco Zola will join him as assistant manager.

Sarri will be hoping to become the first of Abramovich's managers since Jose Mourinho in 2007 to last more than two years in the job, even if his new employers have already laid down the law regarding his conduct.
