Ancelotti eager for Kakuta to pen Chelsea deal
The 19-year-old signed for Chelsea in 2007 but then suffered a broken ankle.
He was banned for four months by FIFA in 2009 for breaching his contract with the French club in order to sign for the Blues. But this fine and Chelsea's subsequent ban on signing players for two transfer windows was eventually quashed by the Court of Arbitration for Sport.
But his future is again on the agenda with his current deal set to expire next summer.
"I don't discuss the salary of players," said Ancelotti. "Technically, it's best for Kakuta - he's young, he's trying to improve and we're the best team for him to stay with.
"He has to take a decision to sign or not. We're sure he'll sign because he's an intelligent player and an intelligent man."
