Gattuso warns his former team-mate, Andrea Pirlo on his appointment as Juventus coach

Gennaro Gattuso warned Juventus head coach Andrea Pirlo who has been named new manager of Juventus.

Pirlo, who has not had a coaching job and only took over as Juve's Under-23s boss last week, was handed the reins in Turin on Saturday in the wake of Maurizio Sarri's dismissal.

Sarri was sacked after just a single season in the job, after leading the Serie A champions to defeat to Lyon in their Champions League last-16 tie the previous evening.

"Well he's screwed now… That's the job," Gattuso told Sky Italia following Napoli's defeat to Barcelona in the Champions League on Saturday.

"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."

Gattuso, who played alongside Pirlo at Milan and for Italy added:  

"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."

Gattuso replaced Carlo Ancelotti and he guided Napoli to the Coppa Italia title this term.
