Yes, I agree that zambrotta's departure was most dissapointing than the others...
Emo, Thuram, even Canna's (don't need to mention Ibra's) departures didn't come close.
We are not talking about the best player with the talents or not, he was with us for like 5 seasons and was easily the most consistent player we had with no complaints during his time and always gave his all for our cause. Then he just ended it abruptly like some sort of jilted lover.... it pains. And he still had a lot to give and could've become a juventus legend like ale. C'est la vie.
