New York City FC midfielder Andrea Pirlo says Antonio Conte is a 24/7 football man.
The Italy coach, 46, is closing in on signing a three-year deal at the Premier League champions and Pirlo believes he will be a success.
Pirlo told the Daily Mirror: "There is a beast in him. I have been in his dressing room at half-time when we have been winning, but he comes in and will be throwing full bottles of water around because of a mistake we made or because he feels we should be further ahead.
"His life is football. I know he is up until 3-4am in the morning, studying videos, looking at errors, studying the opposition of the next game.
"It is a good job Elisabetta is such an understanding wife, and if he takes the Chelsea job then she will have plenty of time to enjoy London, because he has two wives – Elisabetta and football.
"I even know he will turn on the bedroom lights in the middle of the night because he has thought of something he needs to write down – you will not find a more understanding woman than her."
