context matters as always. moggi was banned for life and the club got relegated for activities under his guidance, he's still an obvious legend. turk would probably argue that he bought salas, van der sar, zebina and kovacevic, i'd rather remember del piero, nedved, zidane, buffon etc.
not sure about agnelli. it looks like his own decisions were completely wrong when he was on his own. trusting paratici over marotta, firing coaches left and right, the superleague fiasco, getting himself isolated in italy and europe, letting the club dragged into the mud, that's a lot of mistakes by a supposed legend
marotta in the rookie section though, that's an insult to our 9 year run
