Solid midfield but I wouldn't honestly worry too much about Draxler or Di Maria and Cavani can be handled by Chiellini, with Juve's last night grinta we would have witnessed a similar score and much less ball possession to PSG.
I honestly believe that Barcelona weren't bad but Juve were just too strong, too focused and wanted this more. I was convinced that Barca wouldn't show the same performance like the 1st leg vs PSG and they did not or else this would have been around 5-0 to say the least, they did try to score couple of times and had much more ball possession than against PSG but Juve were just too much and Allegri knew exactly what he was supposed to do and the players did exactly what he asked.
