It was the reverse, broseppi. Can argue who was better between Thuram and Cannavaro (peak Canna was better than peak Thuram, but Thuram was more consistent, didn't have the 2 yrs Canna had with Inter), but Nesta was better than both. He was the best CB of his generation.
Of the CB's: Beckenbauer > Baresi > Scirea > Nesta > Thuram > Cannavaro
Only last two are arguable. If Beckenbauer played today, he'd be a midfielder.
FBs (will include Thuram here too): Maldini > Facchetti > Thuram > Cabrini
Again, the ranking of the last two are debatable, could argue it's the reverse.
Brio (the CB-stopper, was simply called the "stopper") was the bad, Gentile (RB-stopper, the "terzino destro") was the ugly.
Scirea was an extraordinary human being too. Most footballers aren't good role models IMO, but Scirea definitely was.
Don't think that's how it went down. We simply couldn't afford Nesta's transfer fee. Nesta might have had a preference, I don't remember, but that was the primary reason.
