#3 Cutting out his supply line
Allegri started with Matuidi, Betancur and Pjanic in the midfield, but the three of them were busy dealing with the high pressing game of the home side. As such, the long balls for Ronaldo from the midfield were few and far in between.
In fact, the Portuguese was so isolated that he regularly dropped deep, to receive the ball and initiate attacks.
Simeone also ensured that the Dybala-Ronaldo partnership was not allowed to flourish. The Argentinean has the ability to pick out a pass and can be deadly on his day. However, the home side ensured that Dybala had a quiet game too, further piling the misery on Ronaldo.
By the end of the first half, Ronaldo had been at the end of just one ball in the box and as such, he was largely ineffective.
At the start of the second half, he tried to turn provider on a couple of occasions, but Juventus continued to fail to find the final ball. There were a couple of occasions when he got into some space in the box, but he was immediately closed down.
In the dying moments of the game, he did have a chance to steal a vital away goal, but his header from close range was off target.
