As much as I think he's doing a great job for Juventus so far, don't speak too soon. He's on his way to building a great team in Torino but he hasn't won anything yet, if he goes on to achieve as much as Lippi in his time then sure, talk like this is accepted but yeah, for now he's just a very good manager, and I'd actually say he's better than Allegri perhaps tactics wise but crucially at this moment in time Allegri has won a league title already, in a similar space of time in his career.
Same goes for Ancelotti, who got very lucky sure with such an incredible squad at his disposal, but he still went on to win big trophies even if he underachieved in the league (he was competing against a certain Lippi and then later Moratti for most of it). Good luck to Conte and the club sure but, regardless of Lippi's Juventus (and his achievements with said team) being a thing of the past, such a comparison is really, really premature.
