Watford boss Walter Mazzarri sees football as his "art" and revealed his "mind is always on football".
The Italian joined the Hornets during the summer and under his guidance the club have made a solid start to the season, as they sit in 11th spot with eight points from seven games.
Mazzarri likened the work of a football coach to that of an artist and says technology is becoming increasingly important to his methods.
The 55-year-old revealed he uses messaging service WhatsApp to contact assistant Nicolo Frustalupi at all hours and is always thinking about football.
“I might try to watch a film to distract myself but my mind is always on football," he told the London Evening Standard. "WhatsApp has been great for me. I might be in the bathroom, cleaning my teeth, and I’ll have an idea — so I send a voice message to Frustalupi. 'Remind me to speak to Troy Deeney in the morning.'
“In the past, I would write things down on pieces of paper, so I’d remember when I’d wake in the morning. There would be little notes everywhere. I am always thinking about my team, what my players need to do.
“The coach is like an artist and this is my work, my art. I know my players’ characters. I’m available to them 24 hours a day. I speak to them individually and as a group, about tactics and other aspects.
“So I give them a lot of energy. This has always been my way, regardless of where I have worked. If I changed, I wouldn’t be Mazzarri anymore. I’d have to stop.”
