Benitez was named interim boss until the end of the season on Wednesday night and has now begun the challenge of winning round his new club's players and fans, something that could be helped by adding a former Blues star to his coaching staff.
Pierre Zenden told Voetbal International his son was on his way to Chelsea.
"He was approached on Wednesday by Benitez and is now on a flight," he said. "Since yesterday, he phoned Benitez many times.
"I assume that he will be on the pitch this afternoon, together with the manager.
"I assume he will finish the season, just like Benitez."
