Thought Juve were very good there.
Don't know if it was the Juve's intention going into the game to sit deep, but it was apparent from early on the Bologna were intent on attacking and pressing, so Juve did the appropriate thing and took a step back instead of being drawn into an open game.
Taking the step back allowed Juve to slow the tempo of the game and draw Bologna forward before hitting on the counter-attack - which suited the Vucinic-Giovinco front pairing much more than Juve dominating the game usually does.
Aside from the one early cock-up, where the defence tried to hold a line when they ought to have gone with Gilardino's run, there weren't any major issues.
Only criticisms would be that Juve weren't as clinical as they could have been and that they gave away a few more freekicks in dangerous positions than was strictly necessary.
