Personally, I didn't like the way they played football last season. But this is just my personal opinion of course. It depends on the kind of football everyone likes to see.
Juventus doesn't care what people want to see. Maybe that philosophy will change a bit now with Sarri as a coach but throughout history Juventus has always believed in only one motto: "Winning isn't important, it is the only thing that matters!" - Giampiero Boniperti
Well that's true even if you didn't like how they play what matters the most is they still finished at the top of the league table in Serie A. They also showed a good performance in the Champions League. Critics like you are normal to show up once in a while but Juventus won't listen to you as they already have a system that is working for them. Let see if Sarri could make a difference on how they play and maybe after a few games this season you might start to like on how they are playing.
