Eden Hazard will reportedly sign a five-year contract with Chelsea worth around £200,000-a-week.
"He will [sign]," said José Mourinho. "My club always told me that the situation would finish with a new contract, so I was never worried about that."
Mourinho also said Hazard has the potential to become a club legend, but warned: "He needs to win titles."
Mourinho said: "I don't know players who are considered legends in clubs without winning titles, so he has to do that but the potential, I think, everybody knows."
Hazard has been working without an agent on negotiations.
