Chelsea boss Antonio Conte has hailed the impact of former Leicester City midfielder N'Golo Kante.
Conte is also grateful for Claudio Ranieri's advice, particularly on music and eggs.
But the Italians avoided discussing Kante's move from Leicester last summer.
France midfielder Kante was a key figure in the Foxes' Premier League title triumph and has helped Conte's transformation of Chelsea, who are five points clear at the top of the table entering this weekend's fixtures.
Conte said: "I never talked with him about N'Golo. In that case, you are in the market and it is best to think about your team.
"We bought N'Golo because he was fantastic last season with Leicester.
"He is showing with Chelsea that our choice was right to buy him. We paid good money, but his value is good."
He added: "He told me to understand these habits in England. For example, the music in the changing room or before the game that the players want to eat eggs.
"(He told me) To accept them quickly and be focused on the more important aspects."
