Juventus game was indeed not satisfying for anyone. The number of goal attempts they had wasn't much different than the previous game. This time they weren't good enough to finish them up with goals. This look of Juventus make me doubt them about this season also. If we don't see any improvement they may not do better than finishing the season at the 3rd or 4th position. Pogba's absence is felt in their midfield maybe but I don't think it's the only reason.
I think their performance did not disappoint, they made 10 attempted shots and 4 shots on target, besides that they also dominated 53% possession in the match. Juventus were just unlucky because they missed the golden opportunities they created.
The absence of Pogba in the match is not a reason for them to lose, we can see from their match against Sassuolo, they can win easily even without Pogba. But of course, we'll see a better Juventus performance if Pogba later recovers from his injury.
