The 60-year-old was unveiled by Director Fabio Paratici on Thursday morning at a press conference in Turin.
Sarri who managed Napoli for three years before leaving for Chelsea addressed his Neapolitan background.“You need clear ideas on your journey. I supported Napoli because I was born in Naples and I got the idea we could be competitive at a national level, so I gave my all.
”In the last few months at Napoli, I had doubts between my affection for the club and fans, and my professional feeling the journey there had concluded.
”During my doubts, Carlo Ancelotti was introduced and that was probably my fault, as it was my doubt. I received offers, but preferred to go abroad, as I did not want to move directly to another Italian club.
”The Premier League was a great experience, but in the latter half, I felt professional and personal needs to return to Italy.”
On returning to Italy with Juventus, and the challenge ahead –
“Juventus gave me that opportunity and it’s the crowning moment of a career that for 80 per cent of it was extremely tough. I feel that I have respected everyone and I gave my all.
“When Juventus contacted me, the sensation was strong. I’ve never seen a club so determined to get a Coach in my 30 years here and that is what convinced me.
“I think we have a long path ahead of us. I was talking to the President about structures and organisation. Going around English stadiums, you realise how inadequate our arenas are. There needs to be a cultural shift, as you turn behind you on the bench and are surrounded by children.
”I think in terms of club organisation and tactically on the field, we still have the upper hand compared to England.
”I am excited by Serie A this season, because there is the return of Antonio Conte, Marco Giampaolo at Milan, the arrival of an exciting talent like Paulo Fonseca at Roma and at Sassuolo a man I admire a great deal, Roberto De Zerbi. I see a sparkling situation.”
On his choice to join Juve despite them being Napoli’s fierce rivals, he said:
“I had three years at Napoli, I made a choice out of respect to them to go abroad. With the need to come to Italy, I received an offer from Juventus and that’s it.
”In my life, I have respected everyone and given 110 per cent to every jersey I worked with. I’ll do the same with these colours, I cannot do more than 110 per cent.
”My choices were very logical, there’s no need to write a novel around it.
“Clubs are at the end of the day made up of people. I liked the unity I saw in the first approach from Juventus, as that is important for me. At the end of the day, you work for a club and what allows you to give another one per cent is the emotional bond with the people.
”I needed only a couple of meetings with them to realise how determined, strong and with a solid mentality they were. I like that.”
