Absolutely, but a win was needed as a starting point.
You can't go from awful to amazing over night, so you improve little by little.
I hope this game signals a change in tactics from Ferrara.
To Hell with trying and failing to play possession football. Get back to what Juve has done well in recent years: 4-4-2 (or similar) with lots of hard work and good organisation.
At least this way the team is less likely to lose a goal per game on the counter attack.
