Ahead of their home clash with West Ham, he said: "It is not hard to prepare for next season because I'm really confident in my players".
Asked if he was concerned by a report in the Times this week revealing that Abramovich did not pay for an executive box at Stamford Bridge this year for the first time in a decade, Sarri said: "I don't think so".
The 32-year-old has made just seven starts in the Premier League this season and only four appearances in the division since Higuain's arrival in the winter transfer window.
More importantly, Maurizio Sarri will be hoping his side can continue their recent revival and maintain their challenge for a top-four finish.
Chelsea boss Sarri wants to keep the on-loan Juventus forward at Stamford Bridge next term, despite the Blues remaining subject to a Federation Internationale de Football Association two- window transfer ban.
The former Bolton striker also believes constant speculation around the futures of Sarri and Eden Hazard has affected the team's performances.
"I think that he has to improve physically (and) mentally".
"I think they are a really very risky team", said Sarri.

Higuain (31) has three goals in 11 Chelsea games and will cost 36million Euros to sign permanently.
This is going to be a premier league match between Chelsea vs West Ham teams.
Chelsea were hit with the two-window transfer ban by Federation Internationale de Football Association last month, over breaching rules concerning overseas players under the age of 18.
Pressed specifically on whether Hudson-Odoi will keep his place, Sarri said: "I don't know".
"Because, in the season, they were not able to have consistency, but they are a team with high quality". The Hammers lie 11th in the Premier League and looked like a team who were on the beach during their terrible display at home to the Toffees. So I think that, in this moment, they are really very important for us.
"We have only to play every match for winning".
