Maurizio Sarri believes he has a harder job at Chelsea than Carlo Ancelotti does succeeding him at Napoli.

Sarri replaced Antonio Conte as coach at Stamford Bridge in July, having already seen Napoli appoint Ancelotti in his place.

The 59-year-old Italian has made an impressive start with the Blues, who are unbeaten after four League matches, whereas Napoli suffered a heavy 3-0 loss to Sampdoria at the weekend.

However, Sarri is fully aware that Conte secured the Premier League and FA Cup during his two-year spell in charge at Chelsea, while he failed to claim any silverware at Napoli in three seasons.

“I won nothing at Napoli,” he said. “Conte, on the other hand, won here and it’s difficult to take his place.

“What is the hardest thing after moving to Chelsea? I know less about the teams I face and the opponents. At the beginning, to understand it, was not so simple.”

Sarri admits he has no regrets about switching to England and is enjoying the better atmosphere at Premier League grounds.

He added: “Here it is totally different: it is an absolute party, it is a pleasure to arrive in the stadiums and see the fans with different shirts take a beer together. I sign autographs to the fans of the opposing team on the sidelines, before and after the match. There are games with so much intensity, physicality. The English way is a different football from the Italian one, played in extraordinary stadiums.

“How do I see Italy now I live in London? Close up, full of problems. But when we are far away, there is a bit of nostalgia and something is always missing, like the food, although I’m getting used to meat and salmon here.”

Cesc Fabregas is set to hand Sarri a boost by returning to full training with the first-team squad next week. The midfielder has not featured since aggravating a knee injury in the Community Shield last month. He has completed some intense individual sessions this week and hopes to be ready to rejoin the group ahead of the Blues’ match against Cardiff.
