Napoli manager Gennaro Gattuso has explained why Andrea Pirlo is "screwed" after being appointed as Juventus' first-team boss.
Pirlo was announced as the Bianconeri's successor on Saturday, just hours following Maurizio Sarri's sacking after the Old Lady's round of 16 in the UEFA Champions League.
Speaking about his ex-teammate's appointment, Gattuso warned Pirlo that having a great legacy will not help him in management, and that he will not get much sleep.
"He's lucky to be starting at Juventus, but this profession is one where a great playing career is not enough.
"You have to study, to work hard, and you don't get much sleep.
"Being a player and being a coach is really not the same thing at all.
"It's a totally different profession and we can't learn it just from books, we need to get in there and work hard. It's a different world."
