Hazard missed the opening weeks of the season due to a lack of fitness after undergoing ankle surgery at the end of last season.
But he appeared twice as a substitute for Belgium in their recent international fixtures and Antonio Conte said: “Now he is available, he is in the list for the squad.
“He is improving a lot, he is working very strong to be ready. Now I can count on him.
“I have to decide the right minutes, but he is available now.
“When there is a bad injury and surgery, it is normal to pay attention to his recovery.
“Don’t forget he is an important player for us, to play soon.”
