On the note of voting for 1 out of the 50 candidates.
I thought it would be worthwhile to highlight some of the forgotten players and should be big contenders amongst that list. I saw a bunch names as cannavaro, zambrotta, thuram and davids, being thrown but IMO juventus is much more than that and if you dont know the past, then find out. So with a bit of research here are my candidates IMO that should be well ahead of the names I already mentioned:

Now I know, ive never seen these players and some of these players come from an era where it would be difficult to appreciate what they have done, but for those who prefer an alternative to mercenaries, then this list is free from that or atleast from what i know
