The former Juve boss has been lauded for his impact at Stamford Bridge, having transformed a side who defended their title so dismally under Jose Mourinho last season into a team who have only failed to win four of their last 25 games in all competitions.
And Pirlo, who claimed three consecutive Serie A titles under Conte in Turin, says his meticulous approach sets him apart from his rivals.

"Conte, for me, is the best coach because he's a genius," the New York City midfielder told Omnisport.
""He works every day, every single moment for soccer, for the team, every small detail and on the field, the players play very good.
"With Juventus, I was with this coach for three years. We won the league, but every day was stronger in training. Maybe now it's the same at Chelsea."
