Look, Conte because of the 2011-12 season alone is one of the most important figures of the club. He was absolutely instrumental, along with the Stadium, to give the club the adequate mentality back. Let's remember the club was going through its absolute worst moment in history - we're talking about more than 100 years here.
You count in what he did as a player, and the 3 season winning - that's fucking HUGE.
On the other hand, he is clearly obssessed with himself, hugely narcisistic and he downplayed the club many times trying to preserv himself. And the way he left won't be forgotten. His antics are/were disgusting, and also his cowardness, refusing to go from that fucking 352, which set our bar really low at Europe.
But this must be put into context. His antics and narcisistic personality can't erase the huge things he's done to the club. What he did as a player / coach is so much bigger than some of the stupid things he said, or even than they way he left. We must preserve the club's legends, and he's definitely a top legend.
I know Italians are very sentimental, and his lack of loyalty was frustrating. But in the end, it's proabably for the best. Allegri does seem like a better coach at this point, in terms of field work. And that winning mentality Conte instilled was needed when he arrived - now it's in the club, from top to bottom. Now the club transforms guys into winners (like it always did), and not the contrary.
So I say I really really hope he gets a 5 minute standing ovation at the Stadium, and that videos of him winning with the club are shown. This is so much bigger than all that shit talk. Conte is not and will never be an enemy of the club. He really should be appreciated as the legend he is, narcisistic or not. Maybe hiring a narcisistic was exactly what Agnelli had to do at that time.
