The club made this known through their C.E.O, Arrivabene, on Sunday.
According to Arrivabene, the Old Lady are fully behind the tactician for the foreseeable future.
“It would be completely crazy to sack Allegri right now,” he declared.
“Allegri has a project here at Juventus to be developed in the next four years.
“We have a long term project here, I’m involved too as a CEO,” Arrivabene pointed out.
Reports of Allegri losing his job have been more prominent following several losses this season.
Juventus recently lost in the UEFA Champions League to Benfica 1-2 despite taking the lead in the match.
As at time of filing this report, Juventus had lost 1-0 to newly promoted Monza in the Serie A.
