This is not true at all. Juventus did not play defensively against Madrid. In the first half, they were even the better team, to my surprise. The performance from Juventus was shockingly better than I expected. They controlled the game more, they created more chances, and they were calmer on the ball. The only problem was that they didn't know how to break Madrid's defence and score goals.
In the second half, Madrid were better, but still Juventus were very good. They pushed. Anybody who watched that game knows Juventus did not play defensive football. If anything, I can only say they were not daring enough. They preferred to cross.

Juventus lacked an attacker who could make use of the ball. Kolo Muani was one of the reasons Juventus couldn't score. His positioning was also very off.
