Key word is you said hopefully, not that he is a good tactician. Its exactly like it was with Ciro Ferrara, alot of fans projecting optimism and believe in a Juve legend, because he is a Juve legend. Not because of coaching credentials, or coaching ability, which we know nothing about, except that last and only tenure in Serie A turned out badly.
I understand the sentiment, but why let yourself be swayed by it when it relates to as a coach, not the player.
