Much has been made of the role provided by another Chelsea forward, Olivier Giroud, as a link-up player with top goalscorer Eden Hazard, but Sarri says the incoming Higuain, who was coached by the Italian for a single season at Napoli in 2015/16, can act as a foil for the midfielder as well as finding the back of the net.
Guardiola has previously said that he and Sarri are from "the same school" and that education comes from Sacchi. "So I think that Gonzalo will be important for us".
"I speak everyday with Eden, but about his position on the pitch, not about that [transfers]", Sarri told the media, according to FourFourTwo.
"He can score, of course, but he is really very able to play with his team-mates too". I want to see him happy.More news: London Zoo Sumatran tiger Melati killed in fight
"But it's up to him, I think".
"Gonzalo needs confidence first of all".
Sari joked: "I hope I am just a football father - I don't know his mother!" Real Madrid's interest is the worst kept secret in football, with Hazard thought to be keen on signing for Los Blancos.
"I will be really very happy with him if he wants to stay because in my opinion he is the best in Europe".More news: Philippines: measles cases sharply increase in Manila
