Chelsea legend Dennis Wise thinks it is too soon for Frank Lampard to takeover as the club's manager.
The 40-year-old is expected to leave Derby in order to replace Maurizio Sarri at his former stomping ground.
But Wise thinks the move could be premature for a manager with only one season of experience.
Wise told Sky Sports: "Is it too soon for him? I think it is.
"I look at the staff he may bring in as well. Jody may come alongside him and he's a bit inexperienced in a coaching capacity.
"If Frank does come in, he probably needs to bring someone with a bit of experience. There probably will be some changes, because he'll want to bring his own staff in.
"Chris Jones, who was there [at Chelsea] before, is at Derby with him. He's the fitness guy and he's got good experience. But on the coaching side of things I worry.
"Frank, from a playing and personal point of view, everyone loves him at Chelsea, but he hasn't been long in coaching, and neither has Jody. It worries me a little bit, but if they get it I wish them all the luck.
"It's going to be tough for them, but fingers crossed they do the right thing for Chelsea."
