Prandelli started great for Italy and is a good coach, but I think it might be time for him to resign. Spalletti and Montella could be the main candidates, maybe Donadoni or Guidolin.
Prandelli was not a better coach than Lippi, but was like a breath of fresh air, I think Italy desperately need that just like four years ago. Sadly Guidolin and Ancelotti are the unrealistic ones, the offer should be tempting for most of the other Italian coaches, including Conte
