Juventus are extremely balanced & i think they'd progress over Madrid.
I think Juventus is due a very heavy loss soon tbh. Their 3 man backline is just waiting to get ripped apart in Europe. Madrid's pace on the wings would cause them all sorts of trouble. They aren't that great going forward either. They miss a world class striker upfront. Against Donetzk I've watched the highlights and they had 1 shot on target. Which was their goal. And offside. They are drawing so many games for a reason. Sure, they have a certain level of compactness with their midfield controlling games. But I still put them behind Barca, Real, Bayern and Dortmund. Infront of United however. Different story if they had someone like :villa: upfront.
Or maybe I'm just overrating Real Madrid. After all they can barely beat top teams. Last minute winner against a horrible City at home and draw away. Owned by Dortmund twice. Owned by Bayern last season. If teams stop their counterattacks, they can't control games and run out of ideas. Mourinho is a horrible tactician if you think about it.
