Chelsea boss Carlo Ancelotti is calling in a favour from Roberto Mancini ahead of their clash with Manchester City.
Ancelotti has lost all three games with Mancini as Chelsea boss and cannot afford another defeat.
He said: "Roberto was my friend in the Italian team but now he is not such a friend because he has won too many times against me.
"He has to understand you sometimes have to give something to your friends! All three times they have beaten us on the counter-attack."
