Chelsea boss Ancelotti wants Kakuta, Borini to stay
The attacking pair are off contract in June.
"Borini is a young player who has been in the squad many times and was on the bench at Villa," Ancelotti said. "Kakuta is young and trying to improve and show his qualities. He has to make a decision whether to sign or not, but we're sure he'll sign because he's an intelligent player and an intelligent man. He did well against Marseille in the Champions League, but could have done better at Villa – but he is learning.
"He can play up front very well, but his best position is maybe in the middle behind a striker. He just has to improve defensively. You learn that with experience, but I have trust in him. His representatives are speaking with the club about the contract.
"All the young players here know it's not easy featuring regularly in a top team like Chelsea, but they can still improve very quickly by training every day with top players. It's important for them to stay with us and, when they can, play.
"If they decide they want to play regularly, they can ask to go out on loan to another team. If we agree, they can go out on loan for six months or a year."
