I mustve missed something
Two things that stood out to me were disallowing Neymar's goal (although, to be fair, that looked like it hit his arm directly at full speed), and I think he missed a foul on Barca in the build up to their second goal. Have to see that again to be sure, but it looked like there might have been a foul when Barca won the ball. He struck me as bad while I was watching but now that I think about it, it wasn't as bad as I thought. Just be glad that Juve didn't come back to win, because we'd all be trogging about that Neymar handball.
The story of the game was Juve getting killed over and over on the counterattack and Barca couldn't put it away. I mean I think Barca had at least 3 breaks where it was 5 on 3 or 5 on 2. And they were all off of corners. Juve's set pieces were awful all day, and they always led to Barca counters, too.
I also wonder if anything would have been different if Pirlo wasn't playing as the deepest midfielder. That first goal basically came from the space where he should have been, but he didn't track Iniesta, which lead to the 2 on 1 right in front of the goal. Pirlo didn't really influence the game all that much, either. Pogba and Vidal were constantly dribbling up the field instead of Pirlo really dictating the attack.
Fun game, though.
