Maurizio Sarri refused to be drawn on the prospect of Gonzalo Higuain joining Chelsea and says he is not spending his energy on transfers.
Sky in Italy reported Higuain, who is on loan at AC Milan from Juventus, has agreed to move to Stamford Bridge until the end of the season, when they will then have the option to buy the Argentina striker.
Asked by Sky Sports News about how close Higuain was to signing, Sarri replied: "I don't know. I want to be clear, because I cannot help you.
"I spoke with [Chelsea director] Marina [Granovskaia] two weeks ago and she knows my opinion on how to improve the team. Then I decided to be focused on the pitch, on matches, on training.
"Now I am confident because I know Marina is working very hard but I don't know anything about the market because I want to focus on the matches.
"I don't call her every evening, otherwise I spend all my mental energy on the market. I think it's better if I spend it on the pitch."
Cesc Fabregas left Chelsea a week ago for Monaco and the Blues are yet to recruit a replacement, with Zenit St Petersburg's Leandro Paredes linked.
