Legendary Juventus coaches like Trapattoni and Lippi have coached Inter too. Heck, a lot of Italian coaches who've made it to the top have ended up coaching the big 3 clubs of Italian football. Don't see anything different here.
Just because Conte has bad blood with current leadership, doesn't make him any less of a Juventus legend. It's his nature of being a whiny cunt but that doesn't erase the amazing work he's done here both as player and coach.
Zidane is a much bigger legend than Pirlo for example as far as I'm concerned. His best years was with Juventus but unfortunately his most iconic moment at club level was that volley in the 2002 CL final. He is a legend for both Madrid and Juve.
Did calciopolli happened before they appointed them?
Conte and beppe knows how dirty they did us, yet choose to go there.
Seeing Conte hurts a lot, beppe less so but you can't call yourself a juventus legend after doing that.
You chooesed money over dignity and that's fine by me, but you can never be a legend in my eyes, at least.
As for me they are/would be legends all who oversaw as you put it "our legendary run".
Our legendary run has been made possible by legendary people and Tici whether you like it or not is one of them, along with AA, Nedved and Beppe
Edit. I forgot about Conte, who got downgraded after going to that shit club.
Shame about Beppe who took over inda which resulted in his downgrade.
As for zidane. He is a Madrid legend through and through and I doubt few people who are not juventus fans even remember or know that he used to play here.
