The 21 year old has been unavailable since breaking a bone in his foot in mid-October but is hoping to resume training just after Christmas.
The former Roma man was at Stadio Friuli to see his team-mates qualify for the Europa League knockout stages by beating Udinese 1-0 on Thursday, and he is aiming to ensure he can play his part when the competition resumes in February.
"I'm quite good now - working hard every day," he told Liverpool's official website. "The foot is very good and on Monday I see the surgeon to sort out the screws and see if they are taken out or not. On December 26, I'll be back in Liverpool.
"I feel strong. I'm working a lot on the other muscles. I'll start working on my ankle and foot, which is better, and my calf is a lot better."
