Chelsea manager Maurizio Sarri says the only person who can stop him smoking is his father.
The Italian also revealed it was his dad that advised him to join the London club this summer.
"When my father learned I had this offer (from Chelsea), he told me to go to London, that it was the right thing to do," Sarri told Il Mattino.
"He did ask me to stop smoking at least while I'm here. He is the only one who for five minutes can make me wobble in my convictions."
