Italian agent and scout Enrico Fedele believes Maurizio Sarri's football philosophy is the reason why Chelsea want to sign him.
The 59-year-old is expected to take over from Antonio Conte at Stamford Bridge.
He left Napoli after finishing 2nd in the Italian Serie A, just 4 points behind champions Juventus.
"Chelsea? I see Sarri well," Fedele told Tutto Mercato Web.
"Chelsea no longer wants to invest in the market, but on the game.
"The Blues were attracted to Sarri football.
"But there is a need for time and I would not want the rush to be a bad councillor."
