That is the strength that Allegri can revive for Juventus players to be able to work hard and forget all the problems that have befallen them. Allegri is a figure who is able to make Juventus come back strong this season, either before Juventus is penalized or after being penalized by the FIGC.
No one really understands Juventus except Allegri, even after he got sacked couple years ago. And now when he is back, he able to rebuild this team again although they had rough start in the early of season. Going into UCL might be almost impossible for them, but the chance for UEL is quite big, which I'm sure they able to win against Inter in semifinal of Coppa Italia, which the cup winner secures a spot in UEL.
