It was really difficult for me to leave Manchester United. I left for a personal choice.
It doesn't matter if you go somewhere and you're still winning - it's always the wrong decision to leave a club like Manchester United.
Allegri is an easy coach to understand, as he doesn't like to work with stupid people.
You have to win the title with a strong team and a strong defence, but I don't only like to talk about the four defenders and the goalkeeper when you concede goals. It's about the team.
I never forget my first emotions in football, in Sicily.
The minute Juventus came calling, I knew it was the right choice for me. They have the same winning mentality as me.
