Manager Rafa Benitez said: "Cisse said to me he wants to play for the reserves next week. I need to talk with the physio and the doctor but maybe he can play in the reserves next week and then the first team."
He added: "We are surprised but very pleased to see him back because we were thinking maybe he could be back by the end of April, or the end of the season. He is working so hard in training.
And Rafa added he thought the strikers desire for football reflected the hopes of the team as a whole.
He concluded: "It is good for the future that players are working hard and are wanting to come back. It shows they have a good mentality and it is good for us."
