Three days of training in 20 minutes... Andrea Pirlo reveals Chelsea boss Antonio Conte's coaching approach

Andrea Pirlo has opened up about working under Antonio Conte, describing the Chelsea manager as "one of the best" in the world.

The midfielder will retire from playing at the end of the current MLS season in December at the age of 38 and refused to rule out a future role under his former Juventus and Italy coach.

Piro has a professional playing career spanning over two decades, boasting six Serie A titles, two Champions Leagues and the World Cup in 2006, and ranks Conte among the best tutors in the game.

"His attention to detail is impressive," he told Gazzetta dello Sport. "He also manages to give you convincing explanations about things.

"One of his 20-minute video sessions is worth three days on the training ground. You immediately understand what it is you have to do.

"Over the year he improved, with his desire to win and doing everything to the best of his ability.

"He is one of the best, absolutely."
