The influential Reds midfielder has impressed Benitez in recent games, and the manager is now eager to extend the German midfielders contract.
Benitez said: "I don't think he will leave and he has indicated to me that he wants to stay here. All managers would want a player like him. He is a great professional and does a great job for us".
He added: “I talked with Hamann and his agent two months ago. The idea was to talk to him and his agent as soon as possible again to see what is best for the player and the club. The question is when. I am very happy with him and we will talk soon, but now is not the right time."
