Who was the best Italian National team of all time?

So in your opinion what was the best Italian National team (Azzuri) of all time? 1970, 1990, 1998, 2002 or 2006. In My Opinion I think the 1990 team was best it was so impressive because they were an agressive attack minded squad. It had youth that was great coming up (Baggio, Maldini and vets like Schillaci and Donadoni). The 1998 team was also great with Luigi Di Biagio, Dino Baggio, Alessandro Del Piero, Francesco Moriero, Fabio Cannavaro, Gianluca Pesotto, Alessandro Nesta, Christian Vieri, Alessandro Constarcurta, Gianluca Pagliuca, Paolo Maldini, Roberto Baggio, Demetrio Albertini, Filippo Inzaghi, & Angelo Di Livio. The 2002 was great but really underpreformed at was knocked out in the Round of 16 by S.Korea in a dubious way they were regarded as one of the favorites to win the Cup that year. The 2006 won the title but in my opinon even though they were talented they were not the best team in that tourament or in that final game. And the 1970 Squad by many is considered the best Italian national team of all the "Mexican Generation". Enough of my Rambling who do you consider the best Italian National team of all time?
