Their performance is average even with the deduction. It is an ok performance for them. They have been a club for several years to score 90 points and even more than that per season. So even if you add those deducted points back, they wouldn't make it 90 points. They have performed below par and now I wonder what they are going to do to improve the squad for the upcoming season. First and foremost they must try to qualify for the Champions League or otherwise it will be hard to sign any stars. Nobody will go there and not be able to play the Champions League.
if it wasn't for the point deduction surely juventus would be the second team to perform well in serie A this season. but the scandal that hit their team made them get a penalty from the FIGC which made Juventus slightly off balance in the standing table.
Allegri is a great coach he was able to get Juventus back to a good ranking in the standings table where they were almost able to get into the top 4 because the point difference is not too far from the top 4 teams.
juventus still has 2 chances to get a trophy this season namely in the Europa league and in the Italian cup. well, most likely Juventus will focus more on all their strength only for the Europa League and improve their ranking position in the Serie A standings table.
