If Allegri is sacked, then I hope the Juventus board of directors should approach Tuchel as soon as possible. Tuchel should be able to bring Juventus to a better form than now, but I don't want to see Allegri be judged for his team's slump.
I think Juventus can give Allegri a chance until the middle of the season to improve the quality of Juventus. He is still capable of doing it but due to several injuries it has made it difficult for Allgri to make changes. Pogba and Di Maria who were expected to help were unable to play from the start, it has put Allegri in trouble because both players are projected to be able to help Juventus win the title.
Most chances Juventus Board of the Directors are not going to take any decision like this because we are watching already Chelsea made a mistake and paying for this because new coach is unable to bring some quick development and this is going to be the biggest disaster if he fails so same happening here with they all understand current situation injuries are also having problems so with this they need to be more good and give some more time because in last season they were in same situation but at the end Allegri were able to fight back and bring them to better spot, so same can happen.
Thomas Tuchel is surely in good limelight after losing his job from Chelsea and most chances he is going to be related with Bayern Munich which is also in same boat but having some better results in Champions League.
