However, according to the UK Mirror, the Englishman has told his players at the Championship side that he will head to London only when the deal is right.
Initial talks between Derby and the Premier League giants have been held but the Championship side are yet to get a formal offer for their manager.
Derby want £4million in compensation for their manager who is most likely to get a three-year deal by Roman Abramovich.
While reacting to the development Redknapp who is a former Portsmouth, Southampton, West Ham, Tottenham and QPR boss, noted that it will be hard for his nephew to turn down the offer if contacted by Chelsea.
“If Chelsea come calling, it’s a difficult one for him to turn down,” Redknapp told BBC Radio 5 Live. “In my personal opinion, he’ll be the manager of Chelsea.
“It looks to me like it’s going to happen.”
