Chelsea boss Ancelotti fires contract warning at Kakuta
His current deal runs out in June 2011 and manager Ancelotti admits he has no idea if the player will stay.
He said: "I'm not Kakuta, if I have to give an opinion about this I think Kakuta has to stay here and sign a new contract.
“But I'm not involved in this. He is an important player but nobody is indispensable."
