It wasn't our the best performance by far, but I don't see any reasons for the way most of you are panicking here.
Juve was the better team and we should have scored not once. When Udinese scored that was their first shot on goal and that was the moment when we saw buffon for the first time in play as well. So nobody can say that we were worst team, or even they were anywhere close to being remotely equal to Juve. With this kind of performance it would be logical that we won this match, but in football the better team doesn't always win. That is the main moral of the match.
Now, having said that, we still need to learn something from the match. Which is that some players are not that trustworthy and also that we need some creative AM/Trequartista that will help us in unfortunate situations like this. Pogba is not AM or Trequartista and he cannot handle that role any time soon or at all.
